Metadata is the name of the attribute of a document. The concept of metadata is
|
|
divided in two: **metadata types** (size, color, distance) and **metadata values** for
|
|
those types. Metadata types are defined in the setup menu and associated with
|
|
document types. Then when a document is uploaded, a value for that metadata
|
|
can be entered. There are two kinds of metadata type to document type relations:
|
|
optional and required. When a metadata type is optional for a document type,
|
|
it can be left blank for a document being uploaded and the upload will still
|
|
be successful. On the other hand required metadata type must be given a value
|
|
or it will not be possible to upload the document at hand.
|
|
|
|
Examples of metadata type: Invoice number, color, employee id.
|
|
|
|
The data entry of metadata types can be set to allow any value to be provided
|
|
(the default) or a list of possible values can be entered in the ``Lookup``
|
|
configuration option and users will be presented with a drop down list of options
|
|
instead of the default text entry box.
|
|
|
|
If metadata types are setup to allow any value to be entered a ``validation``
|
|
option can be chosen to block the entry of invalid data. Metadata types also
|
|
provide ``parsers`` which will not block the entry of data but are able to
|
|
interpret and modify the value provided by the user to a conform to a specific
|
|
format. An example of a provided parser is the date parser which will interpret
|
|
and correct dates provided by users regardless of the format in which they are
|
|
entered.
