ICSM ISO19115-1 Metadata Best Practice Guide

Resource Maintenance ★★★★

A great deal of geospatial data and service exist as living changing resources. It is often the timeliness that these cycles provide that make these resources so valuable. These update and maintenance schedules are important to document and share so that those who wish to use such resources know how to arrange their work flows to best suit.

Definition

Information about the frequency of resource updates, and the scope of those updates.

ICSM Best Practice Recommendations

Therefore - maintenence information about a citedresource should be documented. This should include descriptions of the update and maintenance frequency and scope.

From class MD_MaintenanceInformation

Discussion

In order for users of a resource to know when the next update will occur or to know how many cycles old a paticular version may be, resource owners and custodians should document in the metadata the maintenance and update frequnency of a resource. If this frequency changes, this change should be reflected in the metadata. If the scope of the update is less than the whole resource, the scope limitation needs to be recorded.

Recommendations

Therefore - custodians of a resource should capture in the metadata the frequensy and scope of update and maintenance of a resource. If none are planned, then record this fact.

Crosswalk considerations

ISO19139

in ISO19115-1 attributes were replaced to provide a more flexible and unambiguous description of maintenance dates and scope.
