• <PROVIDER> is a token like cdl or mdl.
• <DATE> is a string date representation in the form yyyymmdd, for example, "20170209". This is always the date when the relevant event started.
• <TIMESTAMP> is a string timestamp representation in the form yyyymmdd_hhmmss, for example, "20170209_104428". This is always the time when the relevant event started.
• <ACTIVITY> is one of harvest, mapping, enrichment, or indexing.
• <SCHEMA NAME> corresponds to the "name" property of the Avro file schema documented above minus the la.dp.avro prefix.

• plan is for manifests of whole ingests, where the term "plan" refers to the PROV-O notion of a Plan, or sequence of activities. The manifest is a set of JSON objects that documents which Avro files are relevant elsewhere in the provider's folder tree. A Plan can include one or more Activities, so a standalone remapping, for instance, could be part of a Plan with just that one activity. The JSON files in the "plan" directory are written only – they are not modified after being written. They function as a journal of all of the activities that have happened in the particular ingest.

• The files ending in "-prov.json" document which Plan the relevant Avro file belongs to, or which Avro file represents the generator Activity from which the relevant one is derived. For example, if you are looking at a particular mapping Avro file, this can direct you to the harvest Avro file whose records were mapped. This may be redundant with the information in a Plan file, but can make it easier to find things.

• _MANIFEST is a file containing basic information about the activity, such as the source of any input files.
• _LOGS is a directory containing log files that pertain to the activity.
