About the project
The YAMZ Metadictionary (metadata dictionary) prototype is guided by the NSF-funded DataONE Metadata Working Group. The duration of the effort is from June 2013 to July 2014. The prototype is a proof-of-concept web-based software service acting as an open registry of metadata terms from all domains and from all parts of "metadata speech". With no login required, anyone can search for and link to registry term definitions. Anyone can register to be able to login and create terms.
We aim for the metadictionary to become a high-quality cross-domain metadata vocabulary that is directly connected to evolving user needs. Change will be rapid and affordable, with no need for panels of experts to convene and arbitrate to improve it. We expect dramatic simplification compared to the situation today, in which there is an overwhelming number of vocabularies (ontologies) to choose from.
Our hope is that users will be able to find most of the terms they need in one place (one vocabulary namespace), namely, the Metadictionary. This should minimize the need for maintaining expensive crosswalks with other vocabularies and cluttering up expressed metadata with lots of namespace qualifiers. Although it is not our central goal, the vocabulary is shovel-ready for those wishing to create linked data applications.
Across the dictionary there are three disjoint classes. Classification of terms into these categories is a fully-automated process based on voting and user reputation.
