VALEP uses a relational database as well as parsing tools that enable a restrictive use of certain special metadata. A persons, for example, can be identified as the author of a document, only if the person is already stored in VALEPs table of persons. A date is only accepted by VALEP if it is specified in accordance to the socalled EDTF format. On the other hand, (almost) all free text metadata categories enable the usage of the whole range of Unicode symbols in VALEP, e.g. Hong Qian can be alternatively spelled as 洪谦.
Special metadata
List of metadata being used in documents
- Enum specifies a metadata category where the user must choose one value from an internal predefined list
- Name means that the user needs to choose a data set from the table Name that can be edited in the admin section
- Date and Location need to be specified, according to the rules being described above
- Unicode (X) means that the user can specify text using the whole range of Unicode symbols; the text is limited to X characters
- Simple (X) means that the user can specify text only by using a restricted set of characters that include [A … Z] [a … z] [1 … 0] .,;:-+=*/\~#@§$%!?&(){}[]<>|^°´`‘“
- Document Category Enum
