collection_compound.tsv

Sourced from the CFDE-CC Documentation Wiki

Association between a collection and a GlyTouCan ID or a PubChem compound ID (CID) term

For collections with compound metadata, this table will have one row for each compound associated with each such collection.

All fields are required: this table can be empty (header-row only), but any non-header rows must leave no fields blank.

Some examples:

• If you don't have any collections associated with compounds, this table should be left empty.
• If you have exactly one compound associated with each collection, this table will have as many rows as collection.tsv.
• If you have five compounds associated with each collection, this table will have five times as many rows as collection.tsv.
• If some but not all of your collections are associated with one or more compounds, this table will contain one row for each compound assigned to each such collection (and the resulting row count will not have any obvious relationship to the number of rows in collection.tsv, which is both expected and fine in such a case).

Field	Field Description	Required?	Field Value Type	Extra Info
collection_id_namespace	Identifier namespace for this collection [part 1 of 3-component composite primary key]	Required	string	This will be the value of id_namespace in the row in collection.tsv corresponding to the collection referenced in this row. If your program has not registered multiple CFDE identifier namespaces, this will be exactly the same value for all rows.
collection_local_id	The ID of this collection [part 2 of 3-component composite primary key]	Required	string	This will be the value of local_id in the row in collection.tsv corresponding to the collection referenced in this row.
compound	A PubChem or GlyTouCan term ID describing this compound [part 3 of 3-component composite primary key]	Required	string	Example: 753
