PZhao: Lets Discuss Chaining Specifics

We take lots of time to discuss the WCS capability. But we still have no a clear scenario for this service chain demo (maybe I miss something). I think it is time to discuss what services will be used and how to chain them based on the existing service capabilities, not just WCS. PZhao 23 May 2006 (EDT)

I am happy that you brought up this issue. At the last NASA Web Services telecon Liping had a really nice suggestion that I fully subscribe to.

 1. We all expose our respective DATA ACCESS services so the other Chainers can assess our DATA. 
 2. Next we access each others remote data through formal standard interfaces, WCS and/or SOAP
 3. Then we perform WS chaining within our own backyard using our respective  BPEL, SciFlo, WIPE, or DataFed workflow engines
 4. At ESIP:
      a. demonstrate our respective data access and chaining operations; 
      b. we describe our approach and experiences; 
      c. compare with each other's approach and experiences.

This simplification would allow us to make it through the first, obviously very difficult hurdle of accessing each others data. It would also demo service chaining within our own home environments. Based on last Monday's telecon Brian also agreed with the simplified approach to our first interoperability demo.

In order to make a step in this direction we have prepared a somewhat formal description of our data access services as applied to a set of nine "interesting" air quality datasets DataFed_Data_Access_Services.

Liping, please note that these air quality datasets could be potentially useful for the Denver IGARSS06 GSN demo as well. In fact, I stuck a few notes in this regard into the above wiki page. I would like to talk to you more about the GSN demo, possibly before the May 31 telecon. If we play our cards right we may be able to combine this ESIP service chaining effort with the GSN demo. What do you think?

I have gone through your wiki page about air quality data. That is great. We can register these data and services in our catalog and use them in our demo. Do you know any known Web service which can process and overlay these data? If yes, we can definitely chain them in our ESIP and GSN demo.
