Generating text for version controlled documents

Hi,

Having recently undertaken an exercise to generate pages/searchable text for a large volume of PDF documents, I was curious to know what happens "under the hood" in relation to versioning.

Some of the PDFs are quite large and so when a new version is created as a result of the page generation, is a further copy stored in the volume, thus multiplying the effective size of the document? Or does it just store the newly generated text (and corresponding tif image files if it was necessary to generate those to obtain the text)?

Thanks,

Nigel.

Okay, I created a simple PDF only document. I generated pages and received a second version, but the file path on the "electronic document properties" remained the same. It did not change after text generation or reverting to a previous version or deletion of the prior versions. It looks like the document version only tracks the changed components.

It also looks like it never discards a component. I reverted to a version prior to text generation and the text component of the document remained.

So, it looks like you won't blow up you disk space :)

I'm not sure about your use of the word "version." A document can have a number of components, including images, thumbnails, text and an electronic file.

You can turn on versioning for a document, and that will create multiple documents for each change to that document. Creating pages and text occurs on an existing document and does not trigger the creation of a new version. I'm guessing that this is not what you are referring to.

Your PDFs are the electronic file component of the document, they are not the document.

Sorry Nigel, you're right it does create a new version. Yes, your original document with the electronic file is also stored.
