Yes, we've been discussing ideas to implement these. The problem with
metadata as it is right now is that internally it is a dumb text field. If
two separate values are added internally it will still be just one field
with two values concatenated and separated by a delimiter (a comma,
semicolon, etc). The problem is that if one value use the same character as
the delimiter the field doesn't know where one values ends and the next one
begins. This is a a typical problem with structures in databases and the
approach I just explained is what Django itself uses for its mutli values
field, but doesn't work for all cases. One problem with multiple values is
that search feature breaks. The search code would be to interpret the
multiple values of each metadata for each document.
We have talked about adding support for metadata widgets that will filter,
validate and serialize the data from the user for storage and the
deserialze the data to display it in its original form. Widget will allow
setting a metadata value's type: Date, number, string, multi string,
choices. Internally they are all strings but at the UI level different data
types are emulated. Widgets solve the problem of data validation, data type
validation, dependent values,and multi values. Sadly they break search too
as explained above. This feature can't be added until the issue with the
search is solved.
Post by Mark PhillipsAny thoughts on making metadata select boxes have (1) the ability to
select more than one option per metadata, and (2) chained metadata
selections - ie one selection determines the values for the second
selection?
Thanks!

Post by e***@gmail.comWe are keeping the project alive and released a new version based on
direct input and guidance from Roberto. It was released as Mayan EDMS NG
2.8. NG as in Next Generation. It is a 100% compatible fork. We are working
right now on version 3.0.
Post by Mark PhillipsMayan lives in Puerto Rico, and Maria happened. Mayan is still alive and
well, just digging out from under the rubble.
