Hi Andrea, good find, I think it must have been him. He mentioned that he gave a related presentation.

It seems in line with the presentation he gave at INSPIRE 2016, where he mentions the concept of "spatial objects of interest": http://inspire.ec.europa.eu/events/conferences/inspire_2016/pdfs/2016_psessions/29%20THURSDAY_PSESSIONS_H3_16.00-18.00______ADAM%20IWANIAK%202016%20Barcelona4%20-%20final.pdf BTW, his presentation covers some of the issues we have been discussing - in particular, "making data indexable by search engines" - but it also elaborates on how to link spatial metadata and data "on the Web".

This is a brief summary of the (good) discussion and feedback we got. I tried to capture the main points, but for sure I will have failed, so amendments and corrections are very welcome :) Ed, is there a link to the slides that you have shown? We had about 30 attendees. Ed gave an introduction to the working group and its deliverables. The discussion focussed on the Best Practice deliverable as discussed at TPAC. TOPIC: Target audience - Web developers and publishers of data, practioneers - General agreement in the audience TOPIC: SDI and the rest - Need to go beyond SDIs to reach the target audience, the other 99% - Robin Smith, JRC: Needs to be done responsibly to avoid that something like another SDI is created. - Ed: Agreed, it is important not to reinvent the wheel - Markus Jobst, AT: Need the "middleware" to make it work - Jandirk Bules, NL: (not recorded) - Erwin Folmer, NL: need to target the data providers to make sure we can serve the other 99% TOPIC: Spatial things, features and geometry - Different terminology used outside of the GI community - The lighthouse example - "Feature" typically understood as a capability of a software - It is also more blurred whether we talk about a digital abstraction or the real-world entity - Joeri Robbrect, DG ENV: agrees - Markus Jobst, AT: Feels a bit like reinventing the wheel - Robin Smith, JRC: Education is required, but "spatial things" is good because it captures peoples attention - Hugo de Groof, DG ENV: Why not just use "object"? - Alex Ramage, UK: Defnition needs to be clear TOPIC: BP7 - Use persistent HTTP identifiers - Robin Smith, JRC: Context is important, requires understanding of what change means, when does the thing needs a new identifier - Ed: A key aspect is that there is a URI for each identifier - Alex Ramage, UK: Agrees with Robin, e.g. road feature split into parts will receive new identifiers - Clemens: The BP is conceptually consistent with INSPIREs support for persistent identifiers. It mainly is a challenge for those that do not yet manage persistent identifiers and/or to run the infrastructure to resolve feature URIs - Joeri Robbrect, DG ENV: Key is a resolvable identifier that follows the life-cycle of the object - Markus Jobst, AT: When I move the lighthouse or change it to a chapel, does it get a new identifier? - Jandirk Bulens, NL: Different function -> new thing -> new identifier - Straw poll: 50% in the room are responsible for publishing, half of them working with HTTP URIs TOPIC: BP4 - Make data indexable by search engines - Is it practicable? No comment from the audience. - Is it understood? - Erwin Folmer, NL: More than just an HTML page is needed (annotations etc) - Robin Smith, JRC: Geoportals still have their place, where they add value and organise the content - Ed: BPs should be done/doable in addition to current practice of the GI community - Joeri Robbrect, DG ENV: A good approach, goes beyond the current metadata approach in SDIs; need to clarify how it works with, e.g., coverages - Clemens: The search engines also need to clarify how a large number of features should be published so that they will make them discoverable TOPIC: BP8 - Provide geometries in a usable way - Alex Ramage, UK: Support the CRS "you" need or "they" (the users) need. Rather "they"? - Joeri Robbrect, DG ENV: Encoding is always confusing, GeoJSON, JSON-LD, CovJSON. Which encoding to use? On the CRS: ETRS89 vs Web Mercator - Jandirk Bulens, NL: Use what the community has already specified and uses - Clemens: DWBP has recommendation to support multiple encodings, where feasible. CRS: WGS84 most commonly expected/assumed, but also native CRS should be published, often the national CRS TOPIC: BP10 - Spatial semantics for spatial things - Robin Smith, JRC: What is the "best" vocabulary? Examples? Impact on interoperability? - Joeri Robbrect, DG ENV: Points to the ISA Core Location Vocabulary - Clemens: ISA Core Location Vocabulary identifies what is a geometry, but not which vocabulary to use. Could be amended in the future with recommendations, if there is a proper best practice - Jandirk Bulens, NL: Topological relationships are important - Clemens: Yes, current idea to agree on a list of spatial and temporal relationships and register them with IANA - NN: What is the value of publishing spatial data on the web? Value is with publishing objects that are of interest (to the domain). It is different whether you publish data or something that answers a question. TOPIC: List of BPs - Can we identify priorities? Anything not on the list? Anything unclear? - Martin Tuchyňa, SK: There is pressure to have the link to e-government, using linked data. Guidance where to start and where to end is needed. The was a project providing recommendations on this. maybe the BPs could describe a list of steps to be taken. - Joeri Robbrect, DG ENV: Add BP to publish multiple encodings - Clemens: DWBP covers this, not shown here but is referenced - Roberto Lucchi, Esri: Most BP titels are not really "spatial", which other communities have been successful with these practices? - Erwin Folmer, NL: Two additional BPs: a) How to reuse existing infrastructure, easy steps for data providers. b) Queries are important, but unclear how to query distributed data holdings on the web since there are different APIs (SPARQL, etc). - Robin Smith, JRC: BP14 (publish links to related resources) is key for creating value for the 99% - Alex Ramage, UK: Data user could quickly become a data publisher to someone else. Ed closed the workshop with a call to read look at the wiki, read the document and send comments!

We think it would be relevant to get feedback both from the people already doing "spatial data on the Web" (do the BPs provide a good enough coverage of the issues they had to face and the solutions they adopted?), and those who plan to do them (do the BPs provide clear enough guidance on how to do that?) The idea is also to explain that we're trying to "crack open" their datasets, so that each individual "data item" (spatial thing) is addressable in the Web's information space. Do you think this make sense? The wiki page includes also a tentative agenda. Probably, to get feedback in a more effective way, it would good to have break out sessions on the selected BPs, but I don't know if this is feasible, and it probably depends on how many people will join the workshop. When we had the SDW workshop at INSPIRE 2014 in Aalborg, we had around 150 people attending, and this year we have around 1,000 participants at the INSPIRE conference (more than in 2014). However, since the workshop is on Friday, we may have a smaller audience. Thanks!

This being the situation, probably we should consider having an oral presentation, in case it won't be actually possible to run a workshop. Meanwhile, I submitted a draft proposal. I include below the relevant parts for you to review. Please change it as you see fit. Thanks Andrea ---- WORKSHOP PROPOSAL TITLE: W3C/OGC Spatial Data on the Web Working Group ABSTRACT: The Spatial Data on the Web Working Group (SDW WG) is a joint initiative of the World Wide Web Consortium (W3C) and the Open Geospatial Consortium (OGC) aiming to bridge the geospatial technologies and the Web, thus facilitating the publication and use of spatial data across platforms and communities. In order to achieve this, the SDW WG is working on a set of deliverables, described in the WG Charter (https://www.w3.org/2015/spatial/charter), covering best practices for the publication of spatial data on the Web, based on identified use cases and requirements, plus the standardisation of a set of ontologies (Time Ontology, Semantic Sensor Network Vocabulary, Coverages in Linked Data). The workshop is meant to illustrate the work done so far, by providing an overview of the current version of the deliverables, and to collect feedback from participants on the proposed solutions and open issues. AGENDA: - Introduction & purpose of the workshop - Background and objectives of the SDW WG - Overview of SDW WG deliverables - Breakout sessions - Summary from breakout sessions & conclusions ---- On 09/06/2016 19:09, Clemens Portele wrote: Andrea, while I will likely be in Barcelona on Tuesday and Friday morning, do not make the planning dependent on me.

Just trying a possible outline: - Introduction to SDW WG & purpose of the workshop - Overview of deliverables - Breakout sessions on selected topics from BP / UCR & SDW ontologies - Summary of breakout sessions & conclusions Covering all the deliverables in 1.5 hours is probably too much, but the agenda & the discussion topics could be refined based on the outcomes of the f2f at the TPAC.
