Jeremy introduces joint OGC/W3C group

Jeremy: Rob will bring up TPAC topics and WebVMT

Best Practices revision (Clara Boyd, 15min) ... Initial assessment; Priority activities for October/November

Jeremy: this BP has seen good uptake in community and we are proposing a revision and Clara Boyd, lead editor, will give us a report of her assessment

Clara: I took up editor role for this revision, coming from an accessibility point of view, ensuring people can use this information

<jtandy> * GoToMeeting details: https://www4.gotomeeting.com/join/225942517

Clara: the document is very technical which is needed but could see some improvement for wider audience
... linked data section a bit confusing to read. the document was published a couple years ago now and want to make sure best practices are up to date
... focus on changes that have occurred since
... encourage people come to me about items they would like to see covered that aren't
... looking for interested parties to revise specific sections of interest
... my priority is around making it more accessible and current
... interested to hear about others' initial thoughts

Jeremy: in terms of getting work underway, how do you want to organize the working team? focused meetings every couple weeks, take pass at next draft yourself..?

Clara: holding a workshop session of sorts to get input

<LieberJosh> Would it make sense to make requests for input from individual OGC working groups?

Jeremy: anyone keen to help get Clara started?
... ideally someone with github skills

Joe: I'm willing

Jeremy: we've collated a set of issues...

<jtandy> https://github.com/w3c/sdw/issues/1179

Jeremy: we have outlined some of the things we want to do

<brinkwoman> We could also do some outreach. Ask those we know have implemented our best practices to tell us how they did it and what they have learned. Or a wider call for experiences

Jeremy: agreement best practices themselves and examples need updates
... opportunity for new examples, additional topics should refer to corresponding OGC API work
... what is wrong with SDI? need to update that section. there is a heavy RDF bias although in practice more are using web linking
... tile concepts and coordinate reference systems, schema.org updates...
... Bill wants spatial and non-spatial linked better based on OGC work. GeoJSON for examples
... Rob A has thoughts on JSON-LD context files

<jonyu> i can help with updating examples potentially from some work here in Australia

Jeremy: make them modular and easier to generate/use
... we are looking forward to Clara's perspective
... anything to add?

Clara: no, just encourage people to get involved

Jeremy: when do you expect to get started in earnest?

Clara: in coming weeks

Jeremy: Linda, Ted and I will be working on our recharter as a Working Group and will have a close to final draft next week
... Ted will bring through W3C process and Scott review from OGC side

WebVMT (Rob Smith, 15min) ... TPAC planning; Latest WebVMT demos

Jeremy: demo time!

RobS: WebVMT is about synchronizing video location for the web
... quick intro, there is an editor's draft online

<RobSmith> https://w3c.github.io/sdw/proposals/geotagging/webvmt/

<RobSmith> https://webvmt.org/

RobS: homepage has blog, demos and more digestible than the spec
... it synchronizes out of bound metadata
... there is a metadata format from Motion Imagery Standards Board (MISB) for embedding whereas we would prefer separate linked data and move it to moving object
... direct GPS feed suffers from coverage outages/gaps

[Rob projects screen to share video demo with realtime map showing corresponding location]

<jtandy> * 5 mins Rob :-)

RobS: I have a proposal for test bed 17 for adding mpeg4 and a search engine demo
... you can designate location you are interested in and eliminate videos that do not match
... that is powerful and want to investigate further, seeking sponsors
... any questions?

Jeremy: clearly you have been perfect in your presentation...

RobS: I am planning a breakout session on this subject at W3C TPAC
... I will propose exporting video metadata for the web
... we have been looking at different formats (MISB, GPMF, SRT already in WebVMT)
... WebVMT doesn't seek to replace any format
... trajectory, ascent etc as well as handling sensor representation in scope

<jtandy> (from GoToMeeting chat: @NicholasCar says: I use lots of .srt files for foreign (to me) movies)

RobS: my proposal is to raise issues in github before the breakout session so we can make some meaningful statements and progress there
... interested in guidance from social data

Jeremy: TPAC is 26-30 October and self organized joint meetings prior to that

RobS: yes as well as a preliminary discussion hopefully during SDW group meeting

Jeremy: yes, we intend to get that going and will discuss that next week

RobS: is SDW on TPAC agenda?

Jeremy: no, not yet and need to get that sorted
... happy to get things organized for that breakout session
