These checksums ensure that ingested data has not been altered or damaged. A checksum is a short sequence of bits or bytes that is calculated from the data using an algorithm. If even a single bit of the data changes, the checksum will also change, indicating that the data has been changed unintentionally on the file store. During the file upload, TETHYS calculates and stores md5 and sha512-checksums for each file (see attribute type). * **document_licences** with pivot table 'link_document_licences': -Creative Commons licenses are commonly used to govern the use and distribution of research data.

Such identifiers are precisely defined and described in Tethys RDR under the metadata element "Dataset References" as identifier types: DOI, HANDLE, ISBN, URL, and URN. ([manual, p. 21](https://tethys.at/docs/HandbuchTethys.pdf#page=22)). Self referencing identifiers of a dataset are stored inside the table 'document_identifiers'.
