>> institutional memory and history-writing allowed newer members of our 
>> community to slip into seeing those milestones as the actual origins 
>> of the RDF/SW/Linked Data work. This is a mistake that disconnects us 
>> from how we got here, and can distort our thinking about where we go 
>> next. RDF is a specific project, created under the umbrella of a 
>> particular (if sometimes peculiar) organization, and it is a pity if 
>> we lose track of that project now that it touches three decades. It is 
>> a project intimately tied up with the larger Web project itself, and 
>> one that deserves some kind of ongoing bridge between W3C the 
>> organization, and W3C the wider network of communities of interest who 
>> hang around here on mailing lists. And it is a project that was 
>> substantially underway already in 1997-2000, and whose discussions in 
>> those earliest years also formed the basis for many of the earliest 
>> (and most useful) activities around W3C RDFIG/SWIG as a group.
>>
>> RDF of course is nothing terribly new as an approach to describing 
>> things in a KR or logical manner, and many of its common themes and 
>> challenges have been debated intensely for decades or longer. That is 
>> the point of standards, to find and specify common ground rather than 
>> to invent new things in a committee. Thinking of KR and picking from a 
>> longer list, ... the "What's in a Link" paper 
>> (http://www.dtic.mil/dtic/tr/fulltext/u2/a022584.pdf) dates from 1975. 
>> "Shakespeare's Plays Weren't Written by Him, but by Someone Else of 
>> the Same Name" (https://philpapers.org/rec/HOFSPW) dates from 1982. 
>> These and others demonstrate a longer, larger KR/AI heritage dating 
>> back before the Web, the Internet, and computing into the history of 
>> Philosophy and logic. If you prefer a different heritage, you can 
>> travel back in time through the library world, to the origins of 
>> cataloguing, perhaps the Dewey Decimal and its early fork, the UDC 
>> classification, or the Mundaneum (1912's idea of a search engine; 
>> https://www.slideshare.net/danbri/schemaorg-and-one-hundred-years-of-search 
>> ).
>>
>> This has been a very backwards-looking email, and probably a bit too 
>> self-centered. I have been thinking about what kind of RDF/SW/etc 
>> interest or community group I might still be excited to be part of in 
>> another 10 or 20 years, and about many of our earlier contributors 
>> whose work is all but forgotten today. And then, about lessons for RDF 
>> in 2018?
>>
>> I think the first is that we are at our strongest when we build 
>> bridges between different perspectives and work roles. RDF has roots 
>> in KR, and strong links with academia/science, but also and equally it 
>> has roots in hacker/opensource culture, in the user-centric values of 
>> the library community, and in digital library, opensource and industry 
>> initiatives to integrate information and make data available through 
>> the use of simple standard metadata records. RDF has from the very 
>> outset been grounded in the great technology-meets-society debates of 
>> our time, and perhaps has had most traction when it was closest to 
>> efforts at the core of the Web: browsers and search.
>>
>> Another example that feels quite core to the RDF mission (to me). 
>> Twenty years ago Kjetil Kjernsmo and I were debating how best to use 
>> RDF for rating online misinformation 
>> (https://twitter.com/i/web/status/957841302070222854); this year we're 
>> still discussing that (e.g. via http://schema.org/ClaimReview), but 
>> we're also discussing data portability using shared schemas, data 
>> shapes, and Solid/Inrupt. Part of the problem with RDF's adoption as a 
>> technology is that it sometimes comes across as a bundle of burdens, 
>> not just a simple technology standard. Adopters have sometimes 
>> reported that they feel pressured by our community into jumping 
>> through various hoops - whether around namespaces (use lots! don't 
>> invent your own!), identifiers (always use them for every entity 
>> mentioned, and re-use good ones!), reasoning (don't break it with 
>> scruffy data), data (public, persistent, open, ...), HTTP headers etc. 
>> But the community/society aspect can be a strength too. We are working 
>> with a technology which is at its best when multiple over-lapping 
>> datasets are superimposed, and for that to work well, there has to be 
>> an element of community collaboration that goes beyond the strict 
>> technicalities of the W3C specification.
>>
>> In those earlier years - especially the difficult period through 1999 
>> through until the Semantic Web Activity was kickstarted in 2001 - the 
>> RDF Interest Group was the place to be for RDF stuff. We even had a 
>> few f2f meetups (https://www.w3.org/2001/02/rdfig-f2f/). As the 
>> standards matured and conferences, journals and other fora arose, we 
>> kind of stepped back and the list has become a lot quieter. I don't 
>> think it needs to attempt to be in 2018/9 what it was in the 1990s and 
>> early 2000s, but there may be values, themes and interests than 
>> continue, and that deserve a home. Again in earlier times, RDFIG/SWIG 
>> was an important focus for early (pre standardization even) interop 
>> testing amongst RDF query/database implementors. It was where we 
>> explored common schemas for things like calendar interop. It was where 
>> Brian McBride led much of the issue-tracking work that later fed into 
>> the RDFCore WG. It was where Alistair Miles and others took earlier 
>> RDF Thesaurus designs 
>> (https://www.w3.org/2001/sw/Europe/plan/workpackages/live/esw-wp-8.html) 
>> and reworked them into the earliest versions of SKOS. In 2018, 
>> starting fresh, all of these things would simply be independent W3C 
>> Community Groups. 15-20 years ago, we didn't have that mechanism 
>> available to us, and so everything was squeezed into one big (RDF/SW) 
>> "Interest Group".
>>
>> In practical terms, is there a need for a successor to RDF-DEV, RDFIG 
>> and SWIG? Perhaps not. W3C in 1997-1999 and the early 2000s was a 
>> different place. In many ways the efforts of this community 
>> trail-blazed W3C's subsequent opening up into public-participation 
>> groups, through blogs, wikis, public logged IRC chat, collaborative 
>> technology projects, and suchlike.
>>
>> That is in fact the reason for this week's SWIG shutdown. We have gone 
>> from being ahead of our time (the rest of W3C opened up years later), 
>> to being a kind of legacy historical anachronism, a glitch in the 
>> spreadsheets. The W3C Community Group mechanism, in some ways a result 
>> of our early experiments here with public participation, is just the 
>> modern way of doing this kind of thing, and we should catch up with 
>> the new mechanisms. It simply doesn't make sense any more to have a 
>> public participation Interest Group on W3C's management books in 2018. 
>> In addition, the new CG infrastructure, which many of us have already 
>> been using for related groups, offers facilities that we don't have 
>> for SWIG, including some IP commitments which make it easier to 
>> produce W3C documents together, as well as useful tools like blogs.
>>
>> There are already a ton of W3C Community Groups on all kinds of topics 
>> relating to the interests of folk here. You can check out the list at 
>> https://www.w3.org/community/groups/ if you've not looked recently. It 
>> is a relatively self-service mechanism, if you can get a small group 
>> of interested parties together who'd like to have a group, the 
>> bureacracy is pretty lightweight. That's what I'd like to do here with 
>> the group that began as RDF-DEV, and which was RDFIG and SWIG for many 
>> years.
>>
>> Ok, this mail is too long. I have filled out the proposal form for a 
>> RDF-DEV CG,
>>
>> "RDF-DEV, for developments relating to W3C RDF, including 
>> collaboration around applications, schemas, and past/present/future 
>> related standards. Successor to SWIG/RDFIG."
>>
>> The list creation bot says "CONGRATULATIONS! RDF-DEV is now in our 
>> list of proposed groups with you as the first supporter."
>>
>> See https://www.w3.org/community/groups/proposed/ for the link. I 
>> promise not to send mails this long if the group goes ahead.
>>
>> Regarding mailing lists, I would encourage the W3C team to leave this 
>> one (semantic-web@) alive, alongside public-lod@,  and then we can use 
>> a new rdf-dev@ list bonded to the CG for those who want to collaborate 
>> more closely, e.g. on W3C specs. But I think it's best left to Ralph,
