TDL sends metadata from our members to DPLA quarterly, i.e. every three months. Currently, our harvests are scheduled for January, April, July, and October.

Please note that TDL DPLA onboards new members to TXHub, adds new collections to your institutional harvest, and makes mapping changes during only two of the four quarterly harvest periods – April and October. |

The process of sharing metadata from your repository to DPLA involves several steps:
...
When you join the TDL DPLA aggregation service, we will work with you to establish a metadata mapping that fits your existing metadata, based on the TDL’s metadata guidelines. Together, we will look at your metadata elements and how you use them, and determine how they fit into the DPLA metadata application profile.
We try to use the same mapping for all collections from an individual institution. However, we understand that some collections have unique metadata needs, and we can account for those within your institution’s mapping.
Once it is created, we will use the same metadata mapping every quarter to transform your metadata before sending it to DPLA. However, if your metadata structure changes, or new collections require tweaks to the mapping, we can update it as necessary.
For more information about metadata requirements and mappings, see the TDL DPLA Metadata Guidelines.

3. Ingest - TDL delivers the mapped metadata from all of our contributing members to DPLA in one package. DPLA then collects that metadata, runs some processes to validate and enrich the metadata, and ingests it into their systems. After those processes are complete, and the search index is updated, your records are available in the DPLA portal.
