![Page 15: an INSPIRE discovery service geographic information …inspire.ec.europa.eu/events/conferences/inspire_2014/...Impacts of the new standard for metadata on geographic information (ISO](https://reader034.vdocument.in/reader034/viewer/2022051801/5ae313787f8b9a097a8db5a6/html5/thumbnails/15.jpg)
Metadata creation AND revision date
Using the dateInfo element
! dateStamp is used by lot of catalog (eg. GeoNetwork) to store revision date.

“Point of truth” URL
Metadata linkage could point to the URL of the record in the source catalog
! Marine Community Profile (MCP) added the concept of “point of truth” using the distribution section

IR for INSPIRE
“Use ISO19115/119”“Use of ISO 19139 in the context of a Catalogue Service”
= A conversion from ISO19115-1 to ISO19139 is required and rules need to be defined
