I will try to clarify the distinction between the groups, that I see. I asked early on about the scope of the SDW group, and did not receive the impression that the <map> element might be in scope. I can understand that, even though the <map> element is clearly a type of spatial data intended for the Web, the SDW group seems to focus on Linked Spatial Data, in the Semantic Web sense. Simply put, Linked Data is beyond my understanding. I respect it, but I don't understand it. On the other hand, I think I do understand the idea of linking spatial data for the Web, in the sense of simple hyperlinks, and it is really important. For some years now, I have been encouraging the spatial data community to understand and adopt Web architecture [0] more directly [1]. People generally don't recognize Web architecture for the subtle, global miracle that it is. I think Web maps have the potential to unlock the value in the vast quantities of existing spatial data that will otherwise be zipped up and gradually forgotten as link rot on the Web. The barrier to unlocking that value needs to be lowered so that even Grade 6 kids can put our maps in their Web page. Then we'll be starting to talk! > The Community Group process is there to be used exactly as you are doing > so: gathering ideas and seeing what might need future standardisation - > thank you. However, it is notable that there is at least some overlap in what > you're doing and the OGC/W3C WG [2] that, like your CG, came out of last > year's workshop. I was very excited and proud to participate in the W3C/OGC Linking Geospatial Data workshop last year. As you mention, the ideas some of us discussed there gave rise to the Maps For HTML Community Group [2]. However, it seems that ideas are not worth the paper they are written on. There are other Community Groups which have come and gone dormant [3][4][5][6] in this space, I believe because of the lack of implementation. So, the Maps For HTML Community Group has set out on the path recommended by the W3C and its membership, to prototype and promote the concept of maps and linked spatial data for the Web, with a determination to not go quietly into that good night ;-). > In the last 48 hours, a couple of people have pointed me to your document > at [...] The Use Cases and Requirements document [7] is my attempt to summarize the discussions about the <map> element, held at the Linking Geospatial Data workshop. Comments are welcome. Our objective is to lay out some practical ideas, and iterate on those ideas through implementations, with communications through the CG resources (email), and especially on Github [8]. Once these ideas have been properly socialized (prototyped and discussed), through the Maps4HTML CG and subsequently through the Web Incubator CG (in which many browser representatives participate), I hope we will be in a position to take them to the HTML WG as a proposal. But that's the future, and we don't know what it holds, really. Proof of concept through implementations, first and foremost. > Even so, it would be good to have some liaison/communication between the > two groups. I would be happy to keep the SDW group informed of progress in the Maps4HTML CG if that is desired, and I will endeavour to relate developments in the SDW that I become aware of to the work of the Maps4HTML CG. And indeed, new members to the Maps4HTML CG are always welcome, especially if they think there is some overlap between the groups, they can judge for themselves.
