Possible areas of work
- Work on the Observation, Provenance and Characterisation Data Models
Current progress on Data models
Characterization Data Model Uptake
from Oct 2008 to March 2009
- The Charac DM has been used in various advanced use-cases in order to describe complex data and experiment the fine grain detailled levels of the
model, especialy the Error and Variability maps.
- Various XML instance documents have been sketched out for specific use-cases:
- Polarisation data
- Multiple CCD observations
Observation Data Model
- The Observation container has been designed including Provenance and Characterization Packages.
We developed various XML serialisation examples of Provenance : for a stacked image (association), for a an observation with instrumental Provenance metadata: Telescope and Filter description.
All these exemples results of the Observation / Characterization task group initiated one year ago and have been presented and discussed in Baltimorelast fall .
More recently an example of error maps and resolution map for SLOAN spectra has been built. In that case solutions to provide pointers inside a multiextension dataset containing science data as well as ancillary data is proposed. Work is going on with Igor Chilingarian.
- Current discussions about simplification of Data models are going on (with Alberto Micol and Fabien Chereau).
We plan to slightly modify the Characterisation DM XML schema and to propose a new list for UTYPES .
