It is hardly mainstream, but I recently had the need to tag some EPS files. My understanding is that it is possible to add metadata to the comment and tags (keywords) to this filetype.
I used the DOpus native Edit Metadata to add a comment and several keywords to the attached EPS file. The comment wrote successfully, but the keywords never appeared. I repeated the operation on several more EPS files with the same results. Comment fine; keywords a no-show every attempt.
I then wrote a small script to do the job. The results were identical, but it did allow me to check that the keywords were appearing in the variable that I was the writing to the tags in the file. That proved to be the case with every EPS I tried.
It seems that I cannot write tags to EPS files. I have enclosed the spec of my system in case it is some kind of an update issue in windows. I did find a reference on the web to a problem Microsoft were having writing metadata in EPS files, but unhelpfully the reference did not provide a date.
@auden I am able to tag your test file but there is definitely something strange going on. If I zip the tagged file, the tags disappear and they don't reappear after unzipping. In the following screen shots I zip and unzip alongside a sample jpeg for comparison.
At the moment, I cannot even get Opus to save the tags in Opus and look at them in Opus. I will continue researching, but it seems odd I can write Comments. but not tags
Thanks for your suggestions, people, but after looking into it a bit further, as I do not generally use postscript vector graphics, it's simply easier to convert my EPS files into PDFs. No problems with keywords then and I can add metadata for my needs completely in Opus.
Nearly 30 years since Windows appeared and we are still fretting over postscript files
The further I have gone into this, the more I have learned it is not worth the effort. Illustrator files and metadata are not the happiest bedfellows.
Converting EPS files to PDF is a breeze with Acrobat if you can overcome the font errors in vector graphics. My advice would be that unless you really, really need a vector graphic, rip the EPS into Photoshop and save it out as a PDF (fonts and all).
I'd take finding my EPS files over vector graphics any time.
Still no problems with your script, just carrying on testing as I have a bit of time.
