schemas/VegCore/ERD/VegCore.ERD.mwb: record.authors: moved to traceable because actually, different sections of a denormalized source record may have separate authors (e.g. participants for taxa_sampling_event, identifiers for taxon_determination)

schemas/VegCore/ERD/VegCore.ERD.mwb: record.dataset: split this into the scoping_dataset (which scopes the id_within_dataset) and the attribution_dataset (which provides attribution information)

schemas/VegCore/ERD/VegCore.ERD.mwb: regenerated exports and udpated image map

schemas/VegCore/ERD/VegCore.ERD.mwb: record.authors: changed this to refer only to original data creators such as collectors and identifiers. this way, there is no need to generate a combined party_list of owners+authors for every record, because the record-specific authors list can just point to the same party_list as the collectors or event participants. this is also closer to Brad's meaning, which is specifically "a person or institution responsible for creating the dataset" [+emph].

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.
