ISO-1 for Data Discovery - Mandatory

These attributes are mandatory for ISO-1

Concept Description Dialect (Fit) Paths
Resource Title A short description of the resource. The title should be descriptive enough so that
        when a user is presented with a list of titles the general content of the data set
        can be determined.

Keyword A word or phrase that describes some aspect of a resource. Can be one of several types.

Note: The general identification keywords usually have a type of "theme" and are refered to as "theme keywords". Other types and vocabularies are used for other information.

Metadata Use Constraints Information about how the data may or may not be used after access is granted to assure the protection of privacy or intellectual property. This includes any special restrictions,legal prerequisites, terms and conditions, and/or limitations on using the data set. Data providers may request acknowledgement of the data from users and claim no responsibility for quality and completeness of data.

ISO /*/gmd:metadataConstraints/gmd:MD_LegalConstraints/gmd:otherConstraints/gco:CharacterString

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.
