schemas/VegCore/ERD/VegCore.ERD.mwb: party_list: added array field, which stores an array combining all the list entries. if specified, a trigger will autogenerate party_list_entries from this field. if not specified, it will be autopopulated whenever a party_list_entry is added.

schemas/VegCore/ERD/VegCore.ERD.mwb: added data_owner subclass of party_list_entry, which stores use_conditions for each data_owner of a dataset. dataset: added access_rights (public, private, etc.), use_conditions (citation requirements, etc.).

schemas/VegCore/ERD/VegCore.ERD.mwb.run: record.authors: clarified that this should include all parties who helped create the data record, making it a superset of dataset.data_owners, who receive attribution. clarified that record-specific authors such as collectors and identifiers generally do not receive attribution, although dataset-level authors do (this field includes both).

schemas/VegCore/ERD/VegCore.ERD.mwb.run: record.id_within_dataset: removed instruction to also put this in source.name, because source.name is now optional, and this would not make sense because source does not have a parent pointer

schemas/VegCore/ERD/VegCore.ERD.mwb.run: documented that schema COMMENTs cannot contain ' (used in contractions such as "don't"), because MySQL Workbench cannot escape these properly

schemas/VegCore/ERD/VegCore.ERD.mwb: record: added authors, which stores the people who helped create the data record. this is Brad's data author term (Brad.vegpath.org?attribution.data_author), but actually belongs to the individual data record rather than to an entire data*set* because records may have different authors (collectors, identifiers, etc.). note that schema COMMENTs apparently cannot contain ' (used in contractions such as "don't"), because MySQL Workbench cannot escape these properly.

schemas/VegCore/ERD/VegCore.ERD.mwb: dataset.data_owners: documented that this includes all aggregators through which the data has passed, so that this is equivalent to Brad's data indexers (Brad.vegpath.org?attribution.data_indexer)

fix: schemas/VegCore/ERD/VegCore.ERD.mwb: dataset.parent: fixed example to indicate that the GBIF.ARIZ dataset is contained within a specific GBIF dataset (the parent), but was obtained from the GBIF organization (the dataset_source). ARIZ is then the first_publisher, not the dataset_source.

schemas/VegCore/ERD/VegCore.ERD.mwb: dataset: renamed data_source to dataset_source for clarity

schemas/VegCore/ERD/VegCore.ERD.mwb: dataset.contacts: documented that this is the contact person(s) to ask about attribution questions. there should always be at least one contact person. if unknown, the person loading the data should set this to themselves.
