Documenting Resource Lineage
From Earth Science Information Partners (ESIP)
Understanding how sources are combined or processed to create a new dataset is important knowledge for data users. This knowledge enables users to understand, and evaluate the suitability/applicability of the dataset for a particular purpose. This table contains ISO concepts for documenting the lineage of the resource.

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.
