The IVOA Data Curation and Preservation Interest Group (DCP) aims at sharing best practices and engaging IVOA member projects in the long-term curation and preservation of astronomical data.
A DOI (Digital Object Identifier) identifies sustainable resources and opens new possibilities for indexing, cross-referencing, and data access.
In the global landscape, DOIs can be viewed as an architecture linking resources at different level of granularities and published by different data centers.
A DCP Session was dedicated to DOIs during the College Park IVOA meeting in November 2018 and we decided to work on an IVOA Note to provide the community with a clear snapshot of DOI usage and to extract the best practices (about assignment, granularity, metadata, etc.) and the lessons learnt. A survey about experiments in this area was also conducted within the IVOA community. We will give an overview of this effort by referring to the State of the art, to examples in astronomy and to the discussions we had during the last IVOA meetings and in the Note editorial team.
