Re: [GRIDRPC-WG] GridSolve slides

Dear Hidemoto, Great news. We work with Frederic on them too. We have all material but we need just a couple of minutes to finalize. The last discussions with Yves, Frederic and Gaël (a PhD student who works on a data manager) implies that we think we should update the current version of the proposal. Indeed we think we should reduce the number of grid_rpc data function. That means the read and write functions don't concern the grid_rpc, they are functions for data manager not for the gridrpc. We try to reduce the API to a good structure to manage the data (same as shown at OGF'22). The data management should be delegated (as soon as possible) with this structure behind each gridrpc implementation. We hope to be ready for the next week but all nights are so short :-).

Recharter?
by Yusuke Tanimura 21 May '08

21 May '08

Dear all, I am posting this email on behalf of Hidemoto. Our current chater is out of date and we are being asked to review and update the charter by GFSG. An attached file is a draft recharter document which revised to reflect some of our discussion in OGF22. I think one of the biggest changes would be to specify the time schedule for "A GridRPC Model and API for Middleware Developers" document. DIET team, could you check if this schedule is ok for you? First Draft: 2008-06 Public Comment: 2008-08 (I added) Publication: 2008-12 (I added) If there is any other description to be updted (e.g. Group Focus and Scope), please raise a discussion. Thanks, ----------------------------------------------------- Yusuke Tanimura <yusuke.tanimura(a)aist.go.jp> Information Technology Research Institute, AIST 1-1-1 Umezono, Tsukuba Central 2 Tsukuba City 305-8568, Japan TEL: +81-29-862-6703 / FAX: +81-29-862-6601

Fwd: OGF support for OGC Web Processing Service spec?

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? -hidemoto ---------- Forwarded message ---------- From: <lee(a)aero.org> Date: Wed, May 7, 2008 at 4:21 AM Subject: Re: OGF support for OGC Web Processing Service spec?

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.

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.

(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.
