This repo contains a simple javascript application that lets you easily convert GeoBlacklight 1.0 records to the new OpenGeoMetadata Aardvark schema.
You can select a local file or files, or simply paste your json records (a single record, or an array of records).
If your input records used the old dct_isPartOf_sm field (containing a text string of a collection name), there is an option to automatically generate collection records in Aardvark, as well as links to them from the child records. The new collection records will appear at the end of the output JSON, and tend to aggregate more info than you will really want to include in the collection record, so be sure to edit!
Here's a chart of how each field is handled when generating the collection records:
| FIELD | COLLECTION RECORD HANDLING |
|---|---|
| id | generate new id (like "cugir-collection-17sg4wlp") |
