Facilities and Instruments Description frameworkAbstract accepted by the LISA Scientific Organization Committee: Title: Shared nomenclature and identifiers for telescopes and instruments First author: Perret, E. Contributors: Louys M., Buga M., Lesteven S. ...Institute: Centre de données astronomiques de Strasbourg , CNRS- Unistra UMR 7550 Absctract: In the context of sharing public data, science results are expected to be reproducible and therefore we need full traceability of the origin of the data. On the documentalist side, there is a need to relate instrumental origins to published data. We propose to define a shared nomenclature to index each publication with unique designations for facilities, telescopes and instruments based on the Virtual Observatory work on semantics. This would help the documentalists to check the consistency of the instrumental description in publications or make it more explicit. Observation period, data quality and spectral coverage for instance, may be checked by referencing to a global instrumentation service which gathers the nominal observation parameters for the telescope/facility/instrument involved. Based on this indexation mechanism, then the bibliographic metrics for telescope/instrument usage would be easy to compute, and tracking services like the ESO telescope bibliography database (TelBib) or others would be easier to feed. This paper traces the existing initiatives and propose a facility description framework reusing Virtual Observatory metadata which could be fed by the community. Describing Facilities, Telescopes and InstrumentsThis is a common effort initiated in the Semantics working group, namely with suggestions from Planetary science services at Paris Obseervatory and collaborators. The idea is to identify and gather needs for a homogeneized description and identification of instruments, telescopes, space missions, space crafts, etc. and create a maintained repository of identifiers re-usable by the community for
Existing InitiativesThis page records some of the existing initiatives on the topicUseCasesUse Cases for Facilities descriptionDiscussion for a description schemafrom the usage exposed , we see the facilities and instruments need to be standardized (name , ids ) together with physical features such as spectral range, operational period, field of view, spatial resolution, mode, etc. Nominal feature values for instruments can be used in various services, when the information attached to a dataset ( associated data , catalog , etc) is not available). Use cases exposed above may have 3 levels of usage for instruments/ telecope parameters:
Example of Usage : Missions/ Telescopes X Time line ( Mihaela Buga , CDS)

astronomy.
The basic elements are described in an XML schema document vailable here: XML schema For a Facility Model
