Publishing multiple jpegs in article - File storage

Postby barkas » Fri Feb 23, 2007 4:04 am

Hello.

I am using OJS to publish some journals. Just for the record, the journals are very old (100 years :), discontinued, so OJS is going to act only as a repository and all the submission-review processes are not my concern. The journals are scanned from original material, and are stored as single jpg files, one for each page of the journal articles. So, I have a quite large quantity of files to manage :)
Till now the files are hosted in ad-hoc web application (PHP with MySQL). I am trying to migrate the databases and the files to OJS.
Database migration is done succesfully. I have managed to transfer all the info and currently I can display in each article a number of JPG links equal to the article's pages. Now I need to transfer the files.
Here are my questions:
1) My files have a name of "sth****.jpg" (where sth=something and ***=inc number of files). OJS follows a format of "1-2-1-PB.jpg" for example. Do I have to make the conversions (not possible for that amount of files) or I can leave the original filenames?
2) Can someone explain how OJS stores files? From a few examples I saw that OJS creates lots of directories, according to journal_id, issues etc, which is very complicated. Is there a way to bypass it and retrieve files from a single directory? (or one dir for each journal)
3) Any ideas in general???

I am new to OJS and I am currently working on that problem, but I would like to hear other opinions in parallel to my work.
Thank you in advance.

Hi barkas,

I'd strongly suggest looking into the Articles & Issues import/export plugin, which accepts XML files conforming to plugins/importexport/native/native.dtd for import. Using this import technique will save you a lot of headaches wading through the OJS code and it won't tie you to a particular version of OJS for your import tasks.
