I assume that you know how to OCR the docs, so this is just about SVN integration. > Basically I'd like to have every commit to an SVN repo stop at the > pre-commit (or another more suitable) hook so the submitted files can be > inspected and if needed run through a command line OCR engine.

Anyway, what you want to do is possible, and you might be able to use the pre-commit hook for that, but you shouldn't. The things that you shouldn't do is modify commits on the server, because the client has no way of knowing about this, and the client will never receive a notification that the content of the repository is different from what it sent to the repository itself. Suggestions: 1. You trigger a process that OCRs the PDF in question and then replaces the one in the repository or adds a second one next to it, but in a second commit. You could also batch this process, i.e. run it once at night or things like that. 2. You could simply reject the commit from a pre-commit hook if the file is not OCRed already. This would put it into the user's responsibility to run the OCR on the file before committing it. You also mentioned that you only want to scan "select[ed] documents", you could achieve this using a custom property that you check in one of the processing steps. Greetings from Hamburg!
