| Abstract: |
Astronomers are good at sharing data, but poorer at sharing knowledge.
Almost all astronomical data ends up in open archives, and access to
these is being simplified by the development of the global Virtual
Observatory (VO). This is a great advance, but the fundamental problem
remains that these archives contain only basic observational data, whereas
all the astrophysical interpretation of that data — which source is a
quasar, which a low-mass star, and which an image artefact — is contained
in journal papers, with very little linkage back from the literature to
the original data archives. It is therefore currently impossible for
an astronomer to pose a query like “give me all sources in this data
archive that have been identified as quasars” and this limits the effective
exploitation of these archives, as the user of an archive has no direct
means of taking advantage of the knowledge derived by its previous users.
The AstroDAbis service aims to address this, in a prototype service
enabling astronomers to record annotations and cross-identifications in the
AstroDAbis service, annotating objects in other catalogues. We have
deployed two interfaces to the annotations, namely one astronomy-specific
one using the TAP protocol (Dowler et al. 2011), and a second exploiting generic Linked Open
Data (LOD) and RDF techniques. |
