Re: [Dspace-tech] Bitstream can't be saved...?? Is it possible..??
No. The server has no way of knowing what the client will do with the bits once it has received them. In the case of PDF, I believe that the file can be flagged so that no fully-compliant PDF viewer will permit saving a copy, but it is easy enough to alter one of the open-source viewers to ignore that flag. Besides, the user might tell his browser to save rather than display, and then PDF features will not be involved at all. Or the browser might be something like wget or curl or libwww GET, which are designed specifically to fetch files without looking inside them. You could adjust your web server to refuse service to such agents -- if the agent has not been instructed to lie to the server about its identity, claiming it is (say) Firefox or IE. There are lots of things you can do, but none is really fully effective. The most you can do is raise obstacles for the determined user to step over. All of those obstacles can be overcome with very small effort. I would not take the trouble to raise them. It might be better to consider how you can provide a useful resource in such a way that it is not a big problem if someone saves a copy. -- Mark H.

Vinsenso, You don't have to give the bitstream (PDF) to the user. You can render the PDF on your page through a web service, so the user can see the contents, still retaining the formating of the PDF, without giving the user the bitstream.

Re: [Dspace-tech] Bitstream can't be saved...?? Is it possible..??
Hai claudia, What I want is : The end user can see the full-text of my bitstream (type PDF) but they can't saved it. Is it possible...?? btw, thanks for the answer. Now i know what the function of bitstream format registry. ^^ for additional : I use DSpace 1.5.2 (jspui) and windows server 2003. Claudia Juergen wrote: Hello Vinsenso, it is possible to define which bitstream type can be submitted via the UI and are visible to the end user in the item display. This is done via the bitstream format registry. You can access it as admin via the UI and mark bitstreams as internal for that purpose. Hope that helps Claudia Jürgen -- View this message in context: http://old.nabble.com/Bitstream-can%27t-be-saved...---Is-it-possible..---tp2415p2566.html Sent from the DSpace - Tech mailing list archive at Nabble.com. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
