DAP-2 Implementation Review Summary

Spec reviews:

1. Organization: JPL, – server developer, points out some info that is lacking in spec, and some potential limitations. More...
2. Organization: GMU – 2 recs for spec – (1) add query method for DAP client to identify datasets server is holding, and (2) clarify how ints & bytes are encoded (this encoding clarification is something James Gallagher noted needs to be done). More...
3. Organization: GMU - installed several servers & one DAP client, ingested metadata from DAP servers for supporting metadata search and DAP URL generation. Has several recs for improving the spec – her suggestions need to be discussed with James. More...
4. Organization: IRI – has general operational experience as well as several detailed comments about protocol. Identifies some weaknesses. Overall positive. More...
5. Organization: SCCWRP - spec & some operational experience. Group installed servers and developed own DAP client. Identifies one weakness (no way to handle time values). Overall positive. More...
6. Organization: UAH/ITSC – server development experience & some operational experience. Extended current servers to use ESML to support heterogeneous data formats. Overall positive. More...
7. Organization: SDSC – implemented driver that allows a DAP server to use the SRB (Storage Resource Broker) as a data storage system. With this driver, DAP Servers uses the files stored in SRB as if they were stored on local disk. Overall positive. More...

Operational experience reviews:

1. Organization: SEACOS/SC – SEACOOS OPeNDAP dialog – multiple people in the SEACOOS group wrote about their operational experience. More...
2. Organization: USGS - servers worked okay but had trouble building own client. More...
3. Organization: DLESA – Data Access Working Group for Digital Library for Earth Systems Education has recommended that OPeNDAP be supported in future efforts to supply earth science data to education. More...
4. Organization: US JGOFS DMO - US Joint Global Ocean Flux Study Data Management Office The US JGOFS LAS is here: http://usjgofs.whoi.edu/las -- positive experience. More...
5. Organization: IOUSP - oceanography professor at Oceanographic Inst of the Univ of Sao Paulo(IOUSP) and helping Paulo Nobre from the National Institute for Space Research (INPE) in Brazil. More...
6. Organization: CLS/ARGOS - Direction Oceanographie Spatiale/Departement Produits et Servcices , France. Overall positive experience. More...
7. Organization: IAC - Institute for Atmospheric and Climate Science (IAC), Swiss Federal Institute of Technology, Switzerland. Used servers to share data among a group of atmospheric chemistry modelers. Tried to implement own IDL client but was unsuccessful. Tried to reuse much existing software & libraries for client development but had problems. Overall positive experience with servers. More...
8. Organization: NCDC/NOMADS - modeling portal. Overall positive experience installing and running servers. More...
9. Organization: SSEC - Unidata User committee’s Technical Advisor, University of Wisconsin-Madison, Space Science and Engineering Center, Cooperative Institute for Meteorological Satellite Studies. Overall positive. Makes some points on the benefits of adopting one standard for accessing data. More...

Other:

1. Organization: ISPRS – part of ISO/TC 211. More...
