Data Discovery (DataCite)

From Federation of Earth Science Information Partners

DataCite is an organization whose objective is to develop and support methods of locating, identifying and citing data and other research objects. They develop and support the standards behind persistent identifiers for data; and are the originators of Digital Object Identifiers (DOIs).

In the context of the terminology we use (described below), DataCite is an organization that created a set of recommendations at three levels (described in the schema description document) and an XML schema (a dialect) for implementing those recommendations. The dialect is currently being used in the DataCite search portal and in creating DOI landing pages. The dialect can be useful to communities that are trying to improve the way they share metadata; and the recommendations are useful for communities looking for expert guidance about metadata elements that are applicable to data discovery. The work we are doing explores how those recommendations can be useful for communities that are already using other dialects.

The DataCite Metadata Schema is a list of metadata elements DataCite feels are necessary to maintain accurate and consistent identification of a resource for citation and retrieval purposes. The DataCite Metadata Schema also supplies recommended use instructions. The resource that is being identified can be of any kind, but it is typically a dataset. *Note: DataCite uses the term "dataset" in its broadest sense - including both numerical data, as well as any alternate research data outputs. The recommendation has three parts (termed spirals): mandatory concepts, recommended concepts, and optional concepts.


DataCite Metadata Schema for the Publication and Citation of Research Data - Mandatory

The DataCite Metadata Schema is a list of core metadata properties chosen for the accurate and consistent identification of a resource for citation and retrieval purposes, along with recommended use instructions. The resource that is being identified can be of any kind, but it is typically a dataset. We use the term 'dataset' in its broadest sense. We mean it to include not only numerical data, but any other research data outputs.

DataCite Metadata Schema for the Publication and Citation of Research Data - Optional

The DataCite Metadata Schema is a list of core metadata properties chosen for the accurate and consistent identification of a resource for citation and retrieval purposes, along with recommended use instructions. The resource that is being identified can be of any kind, but it is typically a dataset. We use the term 'dataset' in its broadest sense. We mean it to include not only numerical data, but any other research data outputs.

xPath Note: The xPaths included in this table use several wildcards. // means any path, so //gmd:CI_ResponsibleParty indicates a gmd:CI_ResponsibleParty anywhere in an XML file. /*/ indicates a single level with several possible elements. This usually indicates one of several concrete realizations of an abstract object. For example /*/gmd:identificationInfo could be gmd:MD_Metadata/gmd:identificationInfo or gmi:MI_Metadata/gmd:identificationInfo and gmd:identificationInfo/*/gmd:descriptiveKeywords could be gmd:identificationInfo/gmd:MD_DataIdentification/gmd:descriptiveKeywords or gmd:identificationInfo/srv:SV_ServiceIdentification/gmd:descriptiveKeywords. Fit: The fit of the dialect path with the concept is estimated on a scale of 1 = excellent two-way fit, 2 = one-way fit or some other problem, 3 - extension required.
