Proposed DOI BoF at ADASS

[Arnold Rots]

Apologies if you receive this more than once.

As we are pursuing the switch to DOIs for our PIDs in the Chandra Data
Archive
and started looking at what metadata to add, we though the time has come to
hav
an ADASS BoF on the subject.
Attached is the abstract that I am planning to submit by noon (EDT)
tomorrow.
Any comments are welcome!

Cheers,

  - Arnold

Use of DataCite DOIs for Citing Astronomical Data

Arnold Rots
Raffaele D'Abrusco

Now that data citation has become a mature and accepted concept, there
is a need for a globally accepted mechanism for assigning Persistent
Identifiers (PID) to the cited datasets. About 15 years ago a working
group (ITWG) of the ADEC (the executive committee of the NASA data
centers) defined a PID mechanism based on IVOA identifiers under the
authority of the ADS which was agreed upon with the AAS journals. This
system has served the Chandra Data Archive (CDA) well, but found
limited following and clearly was designed for a limited community
with equally little support.
At this time we do have available globally accepted PID types and data
repositories in astronomy and other fields are generally adopting DOIs
issued by DataCite. These are eminently suitable and provide a good
set of metadata. As the astronomical repositories are beginning to
design and implement the use of these DOIs, this seems the right
moment to meet together and discuss our plans and insights regarding 
their use, in order to attain a certain level of commonality in
approach, which will benefit the discoverability of the cited
datasets and flexibility in their access.
In this respect there are especially three design and implementation
matters that are pertinent:
- The schema used for the DOIs; for instance, STScI currently mints
DOIs that are publication-based, containing pointers to an aggregate
of datasets, while CDA plans to augment these with a separate set of
DOIs associated with single datasets.
- The metadata schema used for astronomical datasets: what elements do
we use and what conventions govern their content; this is particularly
relevant for data discovery directly through DataCite.
- The use of trailing fragments to allow access to components within a
dataset.
