  2. Software Components • INFEO Search B • System providing access to ESA CIP (and other) holdings • Operational Instance at ESA • Test Instance at NASA/SGT • CIP-IMS Facility • Translator to allow CIP client access to IMS holdings (CIP to IMS protocol translator) • Test Instance at NASA/SGT • IMS-CIP Translator • Translator to allow EDG client access to CIP holdings (IMS to CIP protocol translator) • Test Instance at NASA/SGT • EOSDIS Data Gateway (EDG) • Client Interface to IMS Servers • Test Instance at NASA/SGT

  3. Installed Component Base IMS CIP IMS-CIP Translator ESA INFEO Search B Subsystem EDG Gateway CIP-IMS Facility Remote CIP Servers NASA INFEO IMS Servers Underlined Items Installed at NASA/SGT

  4. INFEO • Information for Earth Observation (INFEO) is a distributed software system developed by European Commission and now under ESA’s operational control. • “Consists of a number of software sub-systems, integrated to provide access to and exchange of metadata and information relating to Earth Observation data.” • Currently at Release B – builds on earlier Release A. • NASA/SGT have modified* the Search B sub-system to allow it work with Oracle 9i – installed at NASA/SGT * Modifications to INFEO described in a separate document

  5. INFEO Contd. • InstallationStatus: • Oracle 9i Application Server 1.0.2.2 installed on SUN Solaris • Modified INFEO Search B system installed and configured • Oracle Forms Developer/Server 6i Release 2 for SUN Solaris installed • INFEO Forms can successfully run on Microsoft Windows platform with appropriate Netscape/IE plugin – option not fully tested • Collections Database manually populated with sample ECS data – absence of Oracle Developer 2000 prevents form based population • Successful Collection Search (search and present) • Have a working (CIP-Lite) product translator (modified Isite)

  6. INFEO Contd. • To Do : • Continue testing in collaboration with ESA (machine to machine I/F) • Configure INFEO Search B Web Gateway for HTTP client access • Issues: • Need NASA discussion/approval to make this test-site operational • Need NASA/ESA discussion on which EOSDIS data sets can be made accessible via NASA-INFEO

  7. CIP-IMS Facility • Original software from European Commission. IMS Facility allows CIP users to search data held by IMS Servers • IMS Facility software installed and configured at NASA • SGT has modified and tested software to work with current versions of IMS Software • Work accomplished • Modified to work with the new IK and ODL library - Version 3.2.1 • With EDG 3.2.1, MESSAGE_ID length is limited to 30 characters. IMS Facility was generating longer values causing some IMS Servers to return errors. This was fixed. • Successfully tested Inventory Search (Product Search in CIP’s term) against most of the IMS servers and their dataset. • Successfully tested Browse Request on two data centers.

  8. CIP-IMS Facility Contd. To do: • Automate Valids processing • Continue testing in conjunction with ESA Issues: • Need NASA/ESA discussion on how and who should maintain CIP-IMS Facility operationally. Decision required by either for operational support

  9. IMS-CIP Translator • Software developed by NASA/SGT to allow IMS client access to CIP holdings (via. the INFEO Search B system installed at ESA) • Configured and installed at NASA • Current version tested with EDG Version 3.2.1 (on upstream side) and CIP 2.4 (on downstream side) • Finished: • Successfully tested Search, Browse, & email order with INFEO’s CIP system with selected datasets.

  10. IMS-CIP Translator Contd. • To Do : • Working on coordinating search valids between NASA and ESA systems (working with EDG Ops team & ESA ops team) • Finalize the testing against INFEO. • Issues : • Collection Search returns duplicate collections and collection searches are currently very slow. • Order – We are currently sending e-mail orders to INFEO for onward submission via e-mail to data providers. This needs further discussion. We will need to see if the EDG Client has support for pointing to external URL’s to support ordering. • Need NASA/ESA discussion on how and who should maintain CIP-IMS Facility operationally. Decision required by either for operational support

  11. IMS-CIP Translator Flow of Valids Adverts. (SGML) (After filtering) (4) CIP-IMS Facility INFEO Returned ODL converted to internal format (3) Valids Manager FTP request (2) Collection Search (CIP) (1) Response - Convert to ODL (2) CIP-IMS Facility FTP Site Upload Valids (1) Valids Submission (3) EDG (Science/ Operations) CEOS IDN New Valids (ODL) (4)

  12. Valids Validation Procedure Summary • Validation Procedure has been discussed and agreed upon by EDG Science Operations team and SGT. • SGT will retrieve Collection Descriptors from ESA INFEO (via Collection Search), once every two weeks • check for deleted/new/modified collections • SGT will compare these collections with list currently available from EDG – decide if any changes to be made • If new collection to be added: • Gather valids info. • if complete (4 parameter levels – <category,topic, term, variable>), submit to EDG • if not complete (some INFEO collections have only 3 parameter levels), submit partial data with additional metadata to EDG Science Ops. • EDG Science Ops., in conjunction with POC for new ESA Dataset, will help to reach agreement on how to proceed. • Submit final valids on dataset to EDG.
