Vocabulary for Astronomy & Astrophysics Journal keywords (Version 20081104)
type: ConceptScheme
created: 2008-11-04
creator: IVOA Semantics Working Group
description: This vocabulary is based on a set of keywords maintained jointly by the publishers of the journals Astronomy and Astrophysics (A&A), Monthly Notices of the Royal Astronomical Society (MNRAS) and the Astrophysical Journal (ApJ), and updated on an annual basis. The different journals are slightly inconsistent with each other; we have rather arbitrarily used the 2008 list from the A&A web site. The intended usage of the vocabulary is to tag articles with descriptive keywords to aid searching for articles on a particular topic. The keywords are organised into categories which have been modelled as hierarchical relationships. Additionally, some of the keywords are grouped into collections which has been mirrored in the SKOS version. The vocabulary contains no definitions or related links as these are not provided in the original keyword list, and only a handful of alternative labels and scope notes that are present in the original keyword list.
