Dear Tuan,
Congratulations for your availability and responsiveness.
The near future seems promising regarding coming enhancements to eDocman
I will then wait for the cart and custom fields
Adding the possibility to bind a single document to multiple categories is really a valuable feature.
In the same idea, managing tags would bring a new efficiency level to the search mechanism.
Tags differ from categories in the fact that they are closely relative to the content of the document, whereas categories are a more high level abstraction.
Ex: categories (User Manual, Technical Manual, Spare parts...) <=> tags (Body Type[convertible, sedan, suv...], Fuel Type[diesel, petrol...])
A menu item could be used to manage a list of families of tags (Body Type, Fuel Type, ...)
Another one could manage tags, family based.
The document edition would allow to select multiple tags by document.
Finally, the search module should present to the user a way to restrict the search realm by the selection of families/tags.
I know this is a huge work and needs to be thought deeply before coding anything.
By the way, is there a way to contribute to your work?
Best regards,
Pierre
