Hello,

I run a scientific site, which contains articles, presentations, etc.

After long time of thinking and pondering, and trying different modules, I've stopped on Article module for organizing all the articles.

Then I left my site for a while.

Now, that I think of it, Article module is not what I need. It is a scientific site, about nuclear science, and I will need to upload articles full of formulas, charts, drawings and of course text. I don't think XOOPS has a module that can support it easily, so I realized that my best shot is to use PDF format for all my articles.

Now, what I need is this:

A module that:
A. Allows to easily view PDF files, possibly in a frame. If there is some a built-in way to display PDF files on the net, I will be happy to hear of it.
B. Allows to easily upload PDF files.
C. Supports tags - each article should have a few tags, sort of taxonomy.
D. The module should support browsing the files by categories (tags).

Is there such a module available?

If not, how much would it cost me to modify an existing module to match the criterias? :)

With the news module, you can write a summary then attach a pdf file with this article.

You can also fill meta-description and keywords.

a + b + c : complete
d : need modifications form contact instant-zero.
