[GRIDRPC-WG] Fwd: OGF support for OGC Web Processing Service spec?

Tue May 6 21:02:54 CDT 2008

All,

We've got an invitation for a talk at the upcoming OGC-OGF workshop at
OGF-23 from Craig,  one of the co-chairs.

I think we should give it.

any idea?

All,

As part of the upcoming OGC-OGF workshop in Barcelona at OGF-23, I would
very much like to get a brief overview talk from (ideally ;-) the
SAGA, GridRPC,
and HPC-Basic Profile groups.

The OGF-23 workshop is being coordinated with the OGC Technical Committee
meeting which is taking place the exact same days as OGF-23 but in
Potsdam, Germany.

Hence, while these overview talks will be presented in Barcelona, their primary
audience is intended to be the OGC folks who will be in Potsdam.

OGC represents a potential new user community for OGF grid tools so this is
an important opportunity.  Also, the next OGC Web Services Testbed, OWS-6,
is still in the planning process, and what we discuss in this workshop could
very well be picked up for testing and demonstration by the OWS-6 sponsors
and participants.

Please let me know if your group can provide an overview talk.

Thanks!

All,

This request is an action that came out of this week's OGC-OGF
Collaboration workshop.

 OGC (Open Geospatial Consortium) has just announced version 1.0 of their Web
 Processing Service.  (I've forwarded the press release below.)  I've looked at
 earlier versions of this document and based on my initial
assessments, it seems
that WPS could very possibly map to:

1) HPC-Basic Profile  (How would WPS work w/ JSDL and BES?)
2) GridRPC  (Besides the call-response, could Data Handles be used in WPS?)
 3) SAGA  (Much like the GridRPC package, could there be a WPS package?)

It would be extremely helpful to get others from each of these groups to make
their own assessment.  WPS is a basic request-response mechanism with only basic
 support for managing where the data is.  Depending on who you ask, ~80% of the
 data the human race has collected or generated is geospatial
referenced.  Hence,
 OGC represents a huge user base for geospatial data and, imho, is a natural
 adjacency for grids.  All insights, issues, and comments are desired!

 I know that many of us are very busy and simply will not have time to read an
 86-page document from beginning to end.  But, as with many standards documents,
 the core of the spec is presented in only about ten pages, with the rest of the
 doc being necessary detail to clearly define the spec.  Hence, pages 4-11
 present the WPS overview, and pages 11-48 go into more detail about the three
 main WPS functions: GetCapability, DescribeProcess, and Execute.

Please let me know right away if you can help with this assessment.
I'd like to collect comments in a few weeks.

 Thanks,

 --Craig

 -----------------------------------------------------------------------

 Wayland, Mass., February 22, 2008 - The members of the Open Geospatial
 Consortium, Inc. (OGC) have approved version 1.0 of the OpenGIS(R)
 Web Processing Service (WPS) Interface Standard.

 The WPS standard defines an interface that facilitates the publishing
 of geospatial processes and makes it easier to write software clients
 that can discover and bind to those processes. Processes include any
 algorithm, calculation or model that operates on spatially referenced
 raster or vector data. Publishing means making available
machine-readable binding information as well as human-readable
 metadata that allows service discovery and use.

 A WPS can be used to define calculations as simple as subtracting one
 set of spatially referenced data from another (e.g., determining the
 difference in influenza cases between two different seasons), or as
 complicated as a hydrological model. The data required by the WPS can
 be delivered across a network or it can be made available at the
 server. This interface specification provides mechanisms to identify
 the spatially referenced data required by the calculation, initiate
 the calculation, and manage the output from the calculation so that
 the client can access it.

 The OGC's WPS standard will play an important role in automating
 workflows that involve geospatial data and geoprocessing services.

 The OGC(R) is an international consortium of more than 345
 companies, government agencies, research organizations, and
 universities participating in a consensus process to develop publicly
 available geospatial standards. OpenGIS(R) Standards support
 interoperable solutions that "geo-enable" the Web, wireless
 and location-based services, and mainstream IT. OGC Standards empower
 technology developers to make geospatial information and services
 accessible and useful with any application that needs to be
 geospatially enabled. Visit the OGC website at
http://www.opengeospatial.org/.
