Illustrator Server?

If you succeed in negotiating public server licensing terms with Adobe, come back and let us know.

Failing that, your choices are:

1. Write a desktop- or CEP-based tool that graphics suppliers can use to open the file in Illustrator, automatically extract all of the pertinent information (text frame content and coordinates) via AI’s scripting/C++ API, and uploads that data and the [PDF-compatible] AI file to your online review app to process and display to others.

2. Upload the [PDF-compatible] AI file to your online review app and attempt to extract all the text from the raw PDF data using 3rd-party PDF-reading software (a fairly horrible and not wholly reliable black art).

One other tip: If the original pack copy is available from a third-party data source (e.g. MIS system, Excel spreadsheet), you might consider reconciling that structured source text with the unorganized final text taken from the artwork. Pack copy documents (assuming a consistent machine-readable layout) will contain additional useful information—e.g. field names, glossary texts—which you can use to better identify and organize the extracted text for improved presentation and semi-automatic checks. Also good for detecting text amends and other alterations made to the artwork which may differ to the original pack copy, and flagging those for further attention.
