NDG2 Plymouth 11-12 July 2006 - Peter's notes

Board Meeting

  • Finance - overall exactly on track with budget.
  • Highlight report - mostly on schedule at post-Alpha review. WG group were instrumental in Alpha system integration testing.
  • Next three months: need detailed definition of Beta products. Start playing with Vocab server? Discovery back end is broken, Matt Prichard to work on this. Population!
  • CSML future: Andrew presentation (CSML API and v2). CSML will be used by MetOffice? and other projects, e.g. FP6 MOTIIVE. Read Exeter communique on OGC etc. ( http://www.met-office.gov.uk/informatics/) Development of 'feature types'. GML stable version 3.2. 'Operational affordance' - can only extend one feature type but can inherit properties from multiple...? CSML will deliver core set of base types, derived feature types, basic services (api), schemas, tooling (parser/scanner).
  • So what should DPs do towards CSML? NOCS will be adapting scanner to deliver their HDF data rather than CF-netCDF. BODC is using QXF-read method from Matlab/Java?. Implement CSML v1 for now, then modify for v2. Swath very soon. Parser lets us play with CSML records prior to DX working - use that to help us write our scanner. If going from data->CSML, must write scanner in Python as this encodes the objects and attributes. If going from metadata->CSML, just need to plug in SQL extraction to Python scanner.
  • MOLES future: MOLES is for generating various discovery formats, and will not be driven by external standards e.g. SensorML. x-links to include other docs (XHTML, SensorML, ...) verbatim within MOLES records, e.g for BODC calibration info. Could simplify/thin MOLES... Bryan proposes generating CSML data objects first, then flesh out MOLES from those (then DIF). Several issues to be sorted: Granules and crossover with CSML; schema for Stub-B; add coathanger facility; export to ISO19139; ...
  • Kerstin's job has changed, so Andrew taking over role.
  • MOLES Browse (python) knowledge transfer from Bryan to Dominic/Fabio?. Next stage is to deploy at DPs, configuring.
  • OAI issues with deletion in eXist. Keep with DLESE version or change to...?
  • e-Science All-Hands - no NDG papers... Poster on niESS stand/demo of MOLES browse - Roy certain days?, Mike G all days (free person for stand), Helen to provide poster (from GO-ESSP ppt), Helen/Fabio?, Michael H, Steve P?
  • Potential loss of Ag time on DX due to proposal to DEFRA (Hadley Centre climate impact visualisation), may involve NDG technology. If so Steve Pascoe to take on DX.
  • Need for documentation becoming more pressing...
  • Review outstanding tickets: WG team to lead integration, requesting and testing installs, developing installs that actually work for DPs; move away from central NDG portal, as every DP will have NDG search web service? combine browse/discovery GUIs; remove extra Trac milestones added by individual Products.
  • Future funding? Bryan is now on NERC Information Steering Group (ISG). So Discovery portal will be funded. NERC FAB - flexibility and agility in funding. NDGx...? No chance for NERC Consortium. JISC? Bi-partite proposals. Maintain NDG as group, possibly self-funded. Won't get more funding for population, but maybe for technical issues.

All-Hands Meeting

  • Delivery service (Steve P): ppt run through - bbFTP API in Python, transferring raw files or CSML instances including NDG authentication. Demo on Glue of ftp-like command-line client. Later pybbftp Python functions instead of command-line. May need further web-service DS to add functionality.
  • Vocabulary server (Michael/Roy?): 'what-lists <keyword>?'; populated with BODC Parameter Discovery, BODC Parameter Usage, GCMD Terms, SeaDAT, CF Terms later. Outputs XML for formating with stylesheet. Simple client only on livglue (Liverpool), but WS live at  http://vocab.ndg.nerc.ac.uk/. Roy can make available code for clients to install locally.
  • MOLES Browse GUI (Bryan) demo on Glue ( http://glue.badc.rl.ac.uk/cgi-bin/browse.py). Links in with Ag's DX service, asking you to log in to your local site to give you NDG authorisation to continue into GeoSPLAT. Has security e.g. for COAPEC data.
