The Property Graph metadata file (property-graph-input-versions-metadata.txt) provides information about which Precisely products are used to create specific relationship classes in Property Graph and indicates the versions of these products.

If a Property Graph user has versions of Precisely products that are different from the ones listed in the metadata file, the IDs specified in Property Graph relationships may not be found in the user's data and relationships between the user's products won't be in the Property Graph data.

As an example, the metadata file will report the versions of Master Location Data (MLD geocoding dataset) and Address Fabric that were used to assign the PreciselyID (unique and persistent identifier for an addressable location) in both the primary and secondary key products. If the client platform uses a different version of either MLD or Address Fabric, it is possible that there will be PreciselyIDs (PBKEY values) that will not be found in Property Graph.

The following illustration shows an entry from the metadata file. Note: Values shown below are for illustrative purposes only and do not reflect values from the current product version.
