Metadata on the March

From the days of hard-copy liner notes on music albums, metadata have stood outside a piece or file, while adding to understanding of where it comes from, and some of what needs to be appreciated about its content. In the GLAM sector, the accumulation of accurate metadata for objects is key to the mission of an institution, and its presentation in cataloguing.

Today Wikipedia turns 17, with worlds still to conquer. Zooming out from the individual GLAM object to the ontology in which it is set, one such world becomes apparent: GLAMs use custom ontologies, and those introduce massive incompatibilities. From a recent article by sadads, we quote the observation that "vocabularies needed for many collections, topics and intellectual spaces defy the expectations of the larger professional communities." A job for the encyclopedist, certainly. But the data-minded Wikimedian has the advantages of Wikidata, starting with its multilingual data, and facility with aliases. The controlled vocabulary — sometimes referred to as a "thesaurus" as term of art — simplifies search: if a "spade" must be called that, rather than "shovel", it is easier to find all spade references. That control comes at a cost.

Case studies in that article show what can lie ahead. The schema crosswalk, in jargon, is a potential answer to the GLAM Babel of proliferating and expanding vocabularies. Even if you have no interest in Wikidata as such, simply vocabularies V and W, if both V and W are matched to Wikidata, then a "crosswalk" arises from term v in V to w in W, whenever v and w both match to the same item d in Wikidata.

For metadata mobility, match to Wikidata. It's apparently that simple: infrastructure requirements have turned out, so far, to be challenges that can be met.

Facto Post – Issue 9 – 5 February 2018

m:Grants:Project/ScienceSource is the new ContentMine proposal: please take a look.

Wikidata as Hub

One way of looking at Wikidata relates it to the semantic web concept, around for about as long as Wikipedia, and realised in dozens of distributed Web institutions. It sees Wikidata as supplying central, encyclopedic coverage of linked structured data, and looks ahead to greater support for "federated queries" that draw together information from all parts of the emerging network of websites.

Another perspective might be likened to a photographic negative of that one: Wikidata as an already-functioning Web hub. Over half of its properties are identifiers on other websites. These are Wikidata's "external links", to use Wikipedia terminology: one type for the DOI of a publication, another for the VIAF page of an author, with thousands more such. Wikidata links out to sites that are not nominally part of the semantic web, effectively drawing them into a larger system. The crosswalk possibilities of the systematic construction of these links was covered in Issue 8.

Wikipedia:External links speaks of them as kept "minimal, meritable, and directly relevant to the article." Here Wikidata finds more of a function. On viaf.org one can type a VIAF author identifier into the search box, and find the author page. The Wikidata Resolver tool, these days including Open Street Map, Scholia etc., allows this kind of lookup. The hub tool by maxlath takes a major step further, allowing both lookup and crosswalk to be encoded in a single URL.

Milestone for mix'n'match

Around the time in February when Wikidata clicked past item Q50000000, another milestone was reached: the mix'n'match tool uploaded its 1000th dataset. Concisely defined by its author, Magnus Manske, it works "to match entries in external catalogs to Wikidata". The total number of entries is now well into eight figures, and more are constantly being added: a couple of new catalogs each day is normal.

Since the end of 2013, mix'n'match has gradually come to play a significant part in adding statements to Wikidata. Particularly in areas with the flavour of digital humanities, but datasets can of course be about practically anything. There is a catalog on skyscrapers, and two on spiders.

These days mix'n'match can be used in numerous modes, from the relaxed gamified click through a catalog looking for matches, with prompts, to the fantastically useful and often demanding search across all catalogs. I'll type that again: you can search 1000+ datasets from the simple box at the top right. The drop-down menu top left offers "creation candidates", Magnus's personal favourite. m:Mix'n'match/Manual for more.

For the Wikidatan, a key point is that these matches, however carried out, add statements to Wikidata if, and naturally only if, there is a Wikidata property associated with the catalog. For everyone, however, the hands-on experience of deciding of what is a good match is an education, in a scholarly area, biographical catalogs being particularly fraught. Underpinning recent rapid progress is an open infrastructure for scraping and uploading.

Congratulations to Magnus, our data Stakhanovite!

Hi Leostaley, Thank you very much – glad you like my SVG efforts! Thanks for telling me about Johnson solids, too. Now that Commons allows uploading STL (file format), I plan to move make 3D models directly, like this one.

Nevertheless, if you've lists of their vertices on each of their faces, preferably in anticlockwise/counter-clockwise direction as viewed from outside the polyhedron, I'll try to write a script to generate these models. Cheers, cmɢʟee⎆τaʟκ 02:19, 18 March 2018 (UTC)[reply]

The 100 Skins of the Onion

Open Citations Month, with its eminently guessable hashtag, is upon us. We should be utterly grateful that in the past 12 months, so much data on which papers cite which other papers has been made open, and that Wikidata is playing its part in hosting it as "cites" statements. At the time of writing, there are 15.3M Wikidata items that can do that.

Pulling back to look at open access papers in the large, though, there is is less reason for celebration. Access in theory does not yet equate to practical access. A recent LSE IMPACT blogpost puts that issue down to "heterogeneity". A useful euphemism to save us from thinking that the whole concept doesn't fall into the realm of the oxymoron.

Some home truths: aggregation is not content management, if it falls short on reusability. The PDF file format is wedded to how humans read documents, not how machines ingest them. The salami-slicer is our friend in the current downloading of open access papers, but for a better metaphor, think about skinning an onion, laboriously, 100 times with diminishing returns. There are of the order of 100 major publisher sites hosting open access papers, and the predominant offer there is still a PDF.

From the discoverability angle, Wikidata's bibliographic resources combined with the SPARQL query are superior in principle, by far, to existing keyword searches run over papers. Open access content should be managed into consistent HTML, something that is currently strenuous. The good news, such as it is, would be that much of it is already in XML. The organisational problem of removing further skins from the onion, with sensible prioritisation, is certainly not insuperable. The CORE group (the bloggers in the LSE posting) has some answers, but actually not all that is needed for the text and data mining purposes they highlight. The long tail, or in other words the onion heart when it has become fiddly beyond patience to skin, does call for a pis aller. But the real knack is to do more between the XML and the heart.

Images & templates

Hi!

I've noticed that you are providing some of your illustrations in the form of templates. That is imho usually not a good idea, because it it blocks (other) editors from individual adaptions to articles. For instance they may want to adapt the thumbnail size or some of the subtexts to the situation of an individual article, which is not possible that way. And even if they were to change the template they are likely to create side effects elswhere assuming the template is used in more than one article.--Kmhkmh (talk) 10:08, 27 April 2018 (UTC)[reply]

Hi Kmhkmh, Thanks for your message. I've tried to make the messages customisable using template parameters such as in this image. The advantage of using a template is to maintain consistency between articles using the image. Additionally, when the image is updated, all the captions can be updated at one go. For specific uses of the image, one can link to the image directly without using the template, so I think having these templates do not reduce existing functionality. Cheers, cmɢʟee⎆τaʟκ 15:42, 29 April 2018 (UTC)[reply]

Facto Post – Issue 12 – 28 May 2018

ScienceSource funded

The Wikimedia Foundation announced full funding of the ScienceSource grant proposal from ContentMine on May 18. See the ScienceSource Twitter announcement and 60 second video.

A medical canon?

The proposal includes downloading 30,000 open access papers, aiming (roughly speaking) to create a baseline for medical referencing on Wikipedia. It leaves open the question of how these are to be chosen.

The basic criteria of WP:MEDRS include a concentration on secondary literature. Attention has to be given to the long tail of diseases that receive less current research. The MEDRS guideline supposes that edge cases will have to be handled, and the premature exclusion of publications that would be in those marginal positions would reduce the value of the collection. Prophylaxis misses the point that gate-keeping will be done by an algorithm.

Two well-known but rather different areas where such considerations apply are tropical diseases and alternative medicine. There are also a number of potential downloading troubles, and these were mentioned in Issue 11. There is likely to be a gap, even with the guideline, between conditions taken to be necessary but not sufficient, and conditions sufficient but not necessary, for candidate papers to be included. With around 10,000 recognised medical conditions in standard lists, being comprehensive is demanding. With all of these aspects of the task, ScienceSource will seek community help.

Respecting MEDRS

Facto Post enters its second year, with a Cambridge Blue (OK, Aquamarine) background, a new logo, but no Cambridge blues. On-topic for the ScienceSource project is a project page here. It contains some case studies on how the WP:MEDRS guideline, for the referencing of articles at all related to human health, is applied in typical discussions.

Close to home also, a template, called {{medrs}} for short, is used to express dissatisfaction with particular references. Technology can help with patrolling, and this Petscan query finds over 450 articles where there is at least one use of the template. Of course the template is merely suggesting there is a possible issue with the reliability of a reference. Deciding the truth of the allegation is another matter.

This maintenance issue is one example of where ScienceSource aims to help. Where the reference is to a scientific paper, its type of algorithm could give a pass/fail opinion on such references. It could assist patrollers of medical articles, therefore, with the templated references and more generally. There may be more to proper referencing than that, indeed: context, quite what the statement supported by the reference expresses, prominence and weight. For that kind of consideration, case studies can help. But an algorithm might help to clear the backlog.

Plugging the gaps – Wikimania report

Officially it is "bridging the gaps in knowledge", with Wikimania 2018 in Cape Town paying tribute to the southern African concept of ubuntu to implement it. Besides face-to-face interactions, Wikimedians do need their power sources.

Facto Post interviewed Jdforrester, who has attended every Wikimania, and now works as Senior Product Manager for the Wikimedia Foundation. His take on tackling the gaps in the Wikimedia movement is that "if we were an army, we could march in a column and close up all the gaps". In his view though, that is a faulty metaphor, and it leads to a completely false misunderstanding of the movement, its diversity and different aspirations, and the nature of the work as "fighting" to be done in the open sector. There are many fronts, and as an eventualist he feels the gaps experienced both by editors and by users of Wikimedia content are inevitable. He would like to see a greater emphasis on reuse of content, not simply its volume.

If that may not sound like radicalism, the Decolonizing the Internet conference here organized jointly with Whose Knowledge? can redress the picture. It comes with the claim to be "the first ever conference about centering marginalized knowledge online".

Neglected diseases

What's a Neglected Disease?, ScienceSource video

To grasp the nettle, there are rare diseases, there are tropical diseases and then there are "neglected diseases". Evidently a rare enough disease is likely to be neglected, but neglected disease these days means a disease not rare, but tropical, and most often infectious or parasitic. Rare diseases as a group are dominated, in contrast, by genetic diseases.

A major aspect of neglect is found in tracking drug discovery. Orphan drugs are those developed to treat rare diseases (rare enough not to have market-driven research), but there is some overlap in practice with the WHO's neglected diseases, where snakebite, a "neglected public health issue", is on the list.

From an encyclopedic point of view, lack of research also may mean lack of high-quality references: the core medical literature differs from primary research, since it operates by aggregating trials. This bibliographic deficit clearly hinders Wikipedia's mission. The ScienceSource project is currently addressing this issue, on Wikidata.

Strange

I came across this report - see the "Favorite Sessions" table - I really cannot remember that we even had 10 participants in the room!! Shyamal (talk) 08:00, 26 August 2018 (UTC)[reply]

Thanks, Shyamal – well spotted! That was a long time ago, but if my memory serves me right, the room was so packed people were on the stairs.

How have you been lately? Still illustrating birds? Have you attended other Wikimanias recently? I haven't been as active as before – life's been busy, though a few months back, I was hooked on STL 3D models when they were first allowed on Commons. Cheers, cmɢʟee⎆τaʟκ 20:49, 27 August 2018 (UTC)[reply]

Good to hear Gordon! I am glad to hear that more people attended - my memory was perhaps from the numbers present when I started! I have not been doing too many SVGs of birds - but I did work on a few contour maps with QGIS and opensource DEM data. And I am currently getting another small bunch of people comfortable with Inkscape and SVG editing. Was in fact at the recent Wikimania in Cape Town. I did check out your STL files! Have fun. Shyamal (talk) 04:07, 28 August 2018 (UTC)[reply]

How was Wikimania 2018, Shyamal? Cape Town and Montreal were a bit far – hope to go to the next one in Stockholm.

Quite interesting, I suspect that the overall favorite was perhaps the talk by Joy Buolamwini - see https://www.ajlunited.org/ - of course the area is stunning - especially the flora and the topography. Did not go to Montreal and do not plan to apply for the next. Shyamal (talk) 13:47, 28 August 2018 (UTC)[reply]

Nice to hear that you're doing contour maps. I tried converting DEM data to 3D models, initially assuming a Flat Earth then trying different ways to tesselate a sphere. I found regular grids very wasteful of polygons, though, and read that triangulated irregular networks work better. Do you have any experience with generating them? Cheers, cmɢʟee⎆τaʟκ 13:16, 28 August 2018 (UTC)[reply]

The standard SRTM source data is a regular grid (although that regularity may have been generated/preprocessed using some interpolation). I found that getting nice and lean SVG files with contours is tricky - one needs to run QGIS/GDAL's contouring algorithm - then use mapshaper (which tries curve simplification with constraints to avoid contour intersection) and SVG optimiser to get anything that is nice and smaller than a raster image. I have tried TIN on other kinds of data but they naturally tend to produced jagged contours. Shyamal (talk) 13:35, 28 August 2018 (UTC)[reply]

Thanks, Shyamal. Yeah, I thought it wasn't obvious. Even worse is trying to loft the contours into a 3D surface. Guess I'll leave it to someone else to mess with... cmɢʟee⎆τaʟκ

This plate splines are ideal for smoothness but my luck with running it successfully in QGIS has been bad (and that is country/continent scale unlike presumably your plan to use it at planetary scale!) Shyamal (talk) 06:52, 30 August 2018 (UTC)[reply]

Even at country level, Earth curvature can swamp the difference in elevation. A few years back, a friend and I discussed the relative strengths of mountains and curvature. Using formulas at Circular_segment#Formula gives

h = R ( 1 - cos (s/R) )

We can calculate the rise in the middle relative to the width of the country. Assuming countries are square, width = sqrt(area).

For UK: 6400*(1-cos(sqrt(243e3)/6400))/sqrt(243e3)*100 = 3.8%
Russia: 31%

so it's definitely perceptible.

Using List_of_elevation_extremes_by_country gives the following maximum change in elevation relative to the amount of rise in the middle:

Monaco: 0.14/(6400*(1-cos(sqrt(2.02)/6400)))*100 = 89000% (highest in the world)
Nepal: 77% (likely highest for a decent-sized country)
UK: 7.0%
China: 1.2% (even though it has the largest elevation difference)
Russia: 0.44%
Australia: 0.38% (lowest in the world)

Since I had the length of Chile, I didn't have to assume square-ness: Chile: 0.50%

(Multiply with rise/width percentage for percentage of country width.)

The difference in elevation, however, is almost completely swamped by the curvature, except for crazy ones like Monaco, Nepal and Bhutan!

The science publishing landscape

In an ideal world ... no, bear with your editor for just a minute ... there would be a format for scientific publishing online that was as much a standard as SI units are for the content. Likewise cataloguing publications would not be onerous, because part of the process would be to generate uniform metadata. Without claiming it could be the mythical free lunch, it might be reasonably be argued that sandwiches can be packaged much alike and have barcodes, whatever the fillings.

The best on offer, to stretch the metaphor, is the meal kit option, in the form of XML. Where scientific papers are delivered as XML downloads, you get all the ingredients ready to cook. But have to prepare the actual meal of slow food yourself. See Scholarly HTML for a recent pass at heading off XML with HTML, in other words in the native language of the Web.

The argument from real life is a traditional mixture of frictional forces, vested interests, and the classic irony of the principle of unripe time. On the other hand, discoverability actually diminishes with the prolific progress of science publishing. No, it really doesn't scale. Wikimedia as movement can do something in such cases. We know from open access, we grok the Web, we have our own horse in the HTML race, we have Wikidata and WikiJournal, and we have the chops to act.

Wikidata imaged

Around 2.7 million Wikidata items have an illustrative image. These files, you might say, are Wikimedia's stock images, and if the number is large, it is still only 5% or so of items that have one. All such images are taken from Wikimedia Commons, which has 50 million media files. One key issue is how to expand the stock.

Indeed, there is a tool. WD-FIST exploits the fact that each Wikipedia is differently illustrated, mostly with images from Commons but also with fair use images. An item that has sitelinks but no illustrative image can be tested to see if the linked wikis have a suitable one. This works well for a volunteer who wants to add images at a reasonable scale, and a small amount of SPARQL knowledge goes a long way in producing checklists.

It should be noted, though, that there are currently 53 Wikidata properties that link to Commons, of which P18 for the basic image is just one. WD-FIST prompts the user to add signatures, plaques, pictures of graves and so on. There are a couple of hundred monograms, mostly of historical figures, and this query allows you to view all of them. commons:Category:Monograms and its subcategories provide rich scope for adding more.

And so it is generally. The list of properties linking to Commons does contain a few that concern video and audio files, and rather more for maps. But it contains gems such as P3451 for "nighttime view". Over 1000 of those on Wikidata, but as for so much else, there could be yet more.

Go on. Today is Wikidata's birthday. An illustrative image is always an acceptable gift, so why not add one? You can follow these easy steps: (i) log in at https://tools.wmflabs.org/widar/, (ii) paste the Petscan ID 6263583 into https://tools.wmflabs.org/fist/wdfist/ and click run, and (iii) just add cake.

Community Wishlist Survey this week

May I ask if you have any suggestions for the Community Wishlist Survey? It's open until November 11, 2018, and I suspect you'd have some really good ideas for how to improving the technical tools on Commons. You might want to vote on some of the proposals, too. HLHJ (talk) 03:28, 31 October 2018 (UTC)[reply]

Thanks, HLHJ. I'd requested the following features back in 2016, but not much has come out of it:

I understand the reasoning behind their not wanting to add non-standard features to SVG (2), but think (1) is still relevant. Can I resubmit it?

Ta,
cmɢʟee⎆τaʟκ 15:49, 1 November 2018 (UTC)[reply]

Sorry for hasty reply, but yes, I think the rules say you can resubmit. You might also talk to User:Yurik about it being in-scope of this proposal. HLHJ (talk) 01:40, 2 November 2018 (UTC)[reply]

I think it would be a good fit to explain your use cases. Feel free to edit the proposal to extend it :) --Yurik (talk) 15:34, 2 November 2018 (UTC)[reply]

Yurik, I have done so, but I fear that proposal may be a bit large and vague. There is also meta:Community Wishlist Survey 2019/Multimedia and Commons#Option to embed SVGs as SVGs, which seems not unrelated to your #1, Cmglee. HLHJ (talk) 02:35, 10 November 2018 (UTC)[reply]

Template:Diagonal split header

Hello

Have you noticed how Template:Diagonal split header is displayed changed this past few days ?

Before the line was solid, and now it is dashed ! Perhaps since the last MediaWiki update since there is no update done on the template ?

Do you have an idea of waht to do ?

Regards. --Archimëa (talk) 23:24, 15 November 2018 (UTC)[reply]

I think that part of it is the way that it draws the diagonal "line". It's done as a linear gradient along the diagonal from bottom left to top right, with four stop values hence five bands of colour. Three of these bands are solid - the first and fifth are light grey and extend from lower left to 49.5% along the diagonal and from 50.5% along the diagonal to top right, the third is a darker grey and extends from 49.5% along the diagonal to 50.5%. The second and fourth bands are the actual gradient transitions between the two greys, positioned at 49.5% and 50.5% along the diagonal, but they are zero width so the change from one grey to the other is perceived as sudden, this is what gives a theoretically sharp edge to the third band. With that third band's width being no more than 1% of the length of that diagonal, it follows that if the diagonal is less than 100 pixels long, a solid band cannot be drawn and it will necessarily have points where the paler grey bands seem to touch one another giving a dotted or dashed effect. If the cell concerned is large enough, say 250x250 pixels for a diagonal of 354 pixels (approx.),

B A	C
D	E

we see that the central band is broader (it is now approximately 3.54 pixels wide) and clearly solid. Now imagine making that band so narrow that its width is less than one pixel; it can no longer be drawn solid, but must break into fragments which we perceive as a dashed line. Other than always using large cells, I don't think that there's a universal solution. You could broaden the band by changing the colour stops from 49.5% and 50.5% to 49% and 51% but that would make the line more obtrusive. --Redrose64 🌹 (talk) 10:14, 16 November 2018 (UTC)[reply]

Thank you very much for explaining it so clearly, Redrose64. Indeed, I chose 49.5 and 50.5 to give the most pleasing line (to my eyes) for typical cell sizes; I originally used 49 and 51, but the line was obtrusive.

As you seem to know quite a lot about CSS, would you know how I can work around the problem? One workaround is to have a parameter for an editor to specify (or at least override) these percentages. Is there a way to compute the percentages from the cell width and height in Wikitext?

Archimëa, if it's changed recently without any code change, it could be a web browser update on CSS rendering, or even a graphics driver or operating system update on how it does anti-aliasing. Could you please tell on which table and page you saw this anomaly?

Cheers,
cmɢʟee⎆τaʟκ 12:15, 16 November 2018 (UTC)[reply]

Hello. Thank you all for your help. Amazing explanations !

This behaviour could be seen on every linked pages to the template of Wikipedia in French yesterday, here [1] or here [2]. But as i'm writing this two links, I see the solid lines are back. :O

It could be a Firefox problem. I really apology for this false report. I should have wait at least few days before to ask. --Archimëa (talk) 12:24, 16 November 2018 (UTC)[reply]

No problem, Archimëa; it was good you brought it up. Let me know if you see further issues. Cheers, cmɢʟee⎆τaʟκ 12:38, 16 November 2018 (UTC)[reply]

P.S. Glad to see someone has ported the template to the French Wikipedia. If you can spare some time, as don't speak French, may I trouble you to update the documentation on fr:Modèle:Séparateur_diagonal/Documentation so that it includes the new features on Template:diagonal_split_header/doc, please? Merci beaucoup! cmɢʟee⎆τaʟκ 12:46, 16 November 2018 (UTC)[reply]

FYI, I did this tiny change to have a smoother (and a bti wider) line. It looks ok cross-browser and on old IE apparently. --AntonierCH (talk) 12:57, 16 November 2018 (UTC)[reply]

Thanks, AntonierCH. It looks the same to me – I don't expect 0.5% to change things much – so will leave it to Archimëa to see if it's still a problem. Cheers, cmɢʟee⎆τaʟκ 22:47, 16 November 2018 (UTC)[reply]

Different browsers - even different revisions of the same browser - may produce different results. To the question "is there a way to compute the percentages from the cell width and height in Wikitext?" - the short answer is no. For most table cells, we do not set the dimensions but instead allow the browser to compute them (the algorithm for which is horribly complicated, I'll dig it out if you like). Even when we do set the dimensions explicitly (as in my example), these dimensions cannot be read easily, if at all. --Redrose64 🌹 (talk) 00:32, 17 November 2018 (UTC)[reply]

WikiCite issue

GLAM ♥ data — what is a gallery, library, archive or museum without a catalogue? It follows that Wikidata must love librarians. Bibliography supports students and researchers in any topic, but open and machine-readable bibliographic data even more so, outside the silo. Cue the WikiCite initiative, which was meeting in conference this week, in the Bay Area of California.

In fact there is a broad scope: "Open Knowledge Maps via SPARQL" and the "Sum of All Welsh Literature", identification of research outputs, Library.Link Network and Bibframe 2.0, OSCAR and LUCINDA (who they?), OCLC and Scholia, all these co-exist on the agenda. Certainly more library science is coming Wikidata's way. That poses the question about the other direction: is more Wikimedia technology advancing on libraries? Good point.

Wikimedians generally are not aware of the tech background that can be assumed, unless they are close to current training for librarians. A baseline definition is useful here: "bash, git and OpenRefine". Compare and contrast with pywikibot, GitHub and mix'n'match. Translation: scripting for automation, version control, data set matching and wrangling in the large, are on the agenda also for contemporary library work. Certainly there is some possible common ground here. Time to understand rather more about the motivations that operate in the library sector.

Learning from Zotero

Zotero is free software for reference management by the Center for History and New Media: see Wikipedia:Citing sources with Zotero. It is also an active user community, and has broad-based language support.

Zotero logo

Besides the handiness of Zotero's warehousing of personal citation collections, the Zotero translator underlies the citoid service, at work behind the VisualEditor. Metadata from Wikidata can be imported into Zotero; and in the other direction the zotkat tool from the University of Mannheim allows Zotero bibliographies to be exported to Wikidata, by item creation. With an extra feature to add statements, that route could lead to much development of the focus list (P5008) tagging on Wikidata, by WikiProjects.

Zotero demo video

There is also a large-scale encyclopedic dimension here. The construction of Zotero translators is one facet of Web scraping that has a strong community and open source basis. In that it resembles the less formal mix'n'match import community, and growing networks around other approaches that can integrate datasets into Wikidata, such as the use of OpenRefine.

Looking ahead, the thirtieth birthday of the World Wide Web falls in 2019, and yet the ambition to make webpages routinely readable by machines can still seem an ever-retreating mirage. Wikidata should not only be helping Wikimedia integrate its projects, an ongoing process represented by Structured Data on Commons and lexemes. It should also be acting as a catalyst to bring scraping in from the cold, with institutional strengths as well as resourceful code.
