Here I send you what I have written at my return from the OGC
meeting. You asked me also for a comment on how i think TDWG should
continue working with OGC. I will write that in a later message ok?
By the way... i couldnt find any news announcing the MoU between TDWG
and OGC :(
Report of the July 2007 OGC Technical Committee Meeting
The Open Geospatial Consortium (OGC) held its 61st Technical
Committee and Planning Committee Meetings during the week of July 9,
2007 in Paris. TDWG was there represented by Donald Hobern and Javier
de la Torre who gave two presentations on the Earth Observation and
Natural Resources and Environment Working Group.
OGC Technical Committees meetings are a fundamental tool for OGC
process in building standards and assure interoperability. During a
week, OGC members meet in different working groups, discuss and vote
in the process of making or reviewing standards.
Thanks to the new MoU between TDWG & OGC (link here but I could not
find any news item about this ???) now there can be a representation
of TDWG in every OGC meeting and push the interest from the
biodiversity informatics community in the development of geospatial
In this meeting topics varied from Geographic Markup Language,
coverages, the GEOSS project, Web Map Service, Sensor Web Enables and
many more. During the Earth Observation, Natural Resources &
Environment Working Group Meeting TDWG was presented in two different
presentations from Donald Hobern and Javier de la Torre.
Donald Hobern presented (available here) the TDWG infrastructure
project and GBIF. The new GBIF REST services were presented together
with how TDWG is creating a new set of vocabularies that can be use
by services which data has something to do with biodiversity.
Javier de la Torre presented (available here) the results of the
BioGeoSDI meeting (link http://wiki.tdwg.org/twiki/bin/view/
Geospatial/InteroperabilityWorkshop1) with a presentation that made
emphasis on the use of primary data and niche modelling together with
OGC and TDWG standards.
In the other hand there has been several presentations about the
Global Earth System of Systems (GEOSS) and the pilot projects that
are starting now. GEOSS have recently released their catalog service,
a registry where geographic data providers and services can be found
to create a truly world wide Spatial Data Infrastructure for the
observation of the earth. For the moment only a few services are
registered, but they plan in the upcomming months to complete the
catalog with every service related to the observation of the earth.
Related to the observation of the earth, there is the Sensor Web
Enabled (SWE) working group in OGC that has presented several papers
in their continuos effort to provide an interoperability framework
where all kind of sensors can "talk to each other" in a seamless way.
During the meeting the new OGC interoperability program, OWS-5, was
discussed. This new initiative include more than a hundred
participants with a budget of at least a million dollars. The program
is organized in 6 different threads: Sensor Web Enablement (SWE), Geo
Processing Workflow (GPW), Information Communities' Semantics (ICS),
CAD/GIS/BIM, Agile Geography, Compliance Testing (CITE). Significant
work items include geospatial Web service chaining and workflow,
enhancements to the KML language, practical application of the Sensor
Web, and application of GML to real-world scenarios.
There were also discussions on the so called GeoAPI. Together with
the creation of standards there are efforts to provide APIs that
implement the standards so that different vendor, software producers,
can implement them using the same interfaces. The API is available in
sourceforge and is implemented in Java.
The Web Coverage Service (WCS) was also discussed. There is open
discussions on implementing asynchronous services and the use of SOAP
encodings, although this seems to be a general discussion among all
The meeting about OGC for the Mass was a very crowded one. The aim of
the meeting was to identify current trends on the use of geospatial
information on Internet. Things like GeoRSS, KML, WMS tiling, etc.
Specially interesting is the process of making KML an OGC standard.
This has been included in the OWS-5 initiative.
In general it has been a nice meeting with lot of ongoing
discussions. The OGC procedures seems to work quite well and lots of
discussion papers are being prepared continuously that expand or
improve OGC vision and their standards.
