Description of tasks

D01 - Resource Discovery Study Report

The study report should summarize the studies done in the scope of DS5 on various aspects: ontologies, knowledge bases, metadata extraction and management, VO resource search and queries, ...

D02 - Resource Discovery Prototype 2

Second prototype release for DS5. Mainly based on ontologies developments.

---

T01 - Common interface to CDS services

Design study of a common interface to the CDS services (VizieR, SIMBAD, Aladin). A FTE might be hired.

• Automatic tagging of VizieR tables with standard words from the Vocabulary
• Allow improved descriptions in the Registry
• Search VizieR and SIMBAD using vocabulary words as starting point

This is a cross-DS issue with DS4 task T06.

T02 - Registry query tool

• Switch to registries v1.0 after nov 1st.
• Use standard vocabularies for advanced queries
• Improve link with VOexplorer

T03 - Photometric systems description

• Advanced description of photometric systems used in tabular data
• Link with characterization DM
• Cross-DS with DS4 for SED building

T04 - Ontology of astronomical object types

• Improve the SIMBAD consistency checker *Check measurements consistency WRT object types *Check if inconsistent otypes come from components merging for compound objects *Improve overall speed *Improve the ontology from the checker results
• Develop other use-cases

Collaboration between INAF and CDS.

T05 - Object names recognition

Follow-up of the work on the object names identification in papers.

• Detailed analysis of performances, and history of improvements (batch processing of complete volumes)
• Release stable version 1.0
• SIMBAD update:
  • Automated use of the tool for minor journals
  • Replace SIMBAD console
  • Re-scan past articles
• Compute weight of an object in a paper
• Tag PDF documents with bookmarks and direct links to SIMBAD

T06 - Mapping Editor/MEx

Progress towards Mapping Editor/MEx “usable” versions

• rule set equity, FITS output, user documentation
• UI towards “casual user”
• easy customisation/branding/deployment
• characterization model templates

T07 - RDF Registry/SKUA

• prototype suggestions server (interact with AstroOntology and SIMBAD)
• kick off SKUA project (Semantic Knowledge Underpinning Astronomy)
  • architecture, and Spacebook application

Also work on REST profile and interoperability, and IVOA-related activities: vocabularies; DM and UFI conversations (with François Bonnarel, CDS)

T08 - Discovery of VOEvents in AstroGrid Helioscope and VOExplorer

Address use case to find VOEvents falling in the boundaries of a 2MASS file's bounds, generate followup packets, and link to VOExplorer. This is a cross-DS issue with DS6 T10 on characterization.

• Select test sample of VOEvents: supernovae, microlensing events, some GRBs
• Select test sample of Characterisation files describing 2MASS, DENIS, IRAF, and Schmidt plate observations
• Use ARQ toolkit to program box and polygon SPARQL queries against VOEvents and Characterisation files stored as RDF in MSSL Sesame knowledgebase
• Repeat queries using XQuery with VOEvents and Characterisation files stored as XML in Postgres
• Setup STAP/SEAP infrastructure in the system
• “SemanticScope” discovery of VOEvents using VSTO event ontologies
