Previous Action Items[edit | edit source]

  • Everyone: think of different slices that would be useful subgroups to focus on for grand challenges.
  • Hook: send out email at end of week to solicit contributions to implementation lists

Action Items[edit | edit source]

  • Christine White - Send out a list of options for maintaining the GeoPortal server on AWS. What level of effort will be needed from the Discovery Cluster?

  3. Quoted search terms
  4. Other topics

Notes[edit | edit source]

RFC Status[edit | edit source]

  • Chris merged input from Andy Bingham and Ruth Duerr on DataCasting
  • Want to focus on Atom based technologies in this RFC
  • Steve Richard input - need XML examples
  • We need a table that lists all the key elements of the standard (for this RFC, was added as a summary table in Appendix)
  • Seeking someone to look over / complete the columns of the table / contribute examples
  • Add a collection casting ("access" link type) from NSIDC example
  • Granule level query to some enclosure or OPeNDAP item
  • Some NSIDC links point to ordering page, text file, FTP directory, OPeNDAP server, etc.
  • OPeNDAP dataset level get a directory HTML page or a THREDDS XML file

Collection Level Data Access Points[edit | edit source]

  • Specify a MIME type that would be indicative of OPeNDAP directory
  • Email thread of "x-" vs. "vnd." MIME types
  • Needs more discussion / definition
  • Put together a DCP to put together an OPeNDAP, order pages, and FTP directories, etc.
  • Is this something that's not worth working out at this point?
  • NSIDC has so few datasets that are OPeNDAP that it would not be high priority
  • No current plans to implement OPeNDAP extension for most interested parties. Exclusion is PODAAC.
  • We don't have the resources for the non-OPeNDAP things at this time.
  • James is interested in working on it in the future, defer for one month.
  • Chris may proof of concept for OPeNDAP stuff at GSFC

Phrase Search Terms[edit | edit source]

  • Interest in writing OPeNDAP clients
  • Running into the heterogeneity amongst OPeNDAP servers
  • No standard for how to process more than one word in the search
  • There is no standardization or support for phrase searches
  • Very common thing for major search engines
  • Could put together a short DCP for quote enclosure
  • Would this be too much of a burden for server (Solr and Google supports)
  • This may be an implementation specific construct…
  • Error codes and the use of boolean ("AND"/"OR")
  • Is this quoted phrase behavior a "must" type of behavior or "should"?

Other Topics[edit | edit source]

  • Christine - What to do with GeoPortal implementation (on AWS), incurring monthly fee, no one is actually playing with OpenSearch capabilities. Keep in on Amazon? Move it to Github? Etc…
