I think it would be fantastic i PhotoMechnic could develop inte a more general DAM. With that I mean that it should be possible to tie XMP data to virtually any type of data files. For me it would be fine if it could index content of PDF or Office-documents but it´s not a must.
The reason to this proposal is that many photographers manage their own business and handles all sorts of info today - not just images or video. This has also been a common way for quite a few DAM-companies that that have emerged from the newspaper - publishing - photo world, to get a wider user base and more healthy business, when for example a lot of the papers have gone out of business. PhotoMechanic already has a lot in place for a move like that. It can already handle both different sets of maintenance forms and many different parallell catalogs. What it lacks though is a possibility to handle XMP-data tied to other file types than images and video.
If that would happen a photographer would be able to handle all the documents and images, he or she would need in one single application and make them searchable. Since PhotoMechanic already is used as a front-end together with some enterprise DAM-systems handling images, it would extend the usability when people want to use it even for other document types and other types of schemas. Remember that XMP sands for Extensible Markup Platform so with that in mind it will also call for to be "extensible" in a real sense of been able to customize IPTC/XMP-schemas, which means being able to add your own "fields/elements".
I think this could be a tremendous boost of usability for PhotoMechnic-users and it would make PhotoMechanic even more relevant in a much broader perspective than just for images and open up for use in a lot of other contexts. Camerabits would get a chance to expand into completely new markets that have been closed for them until then. They could diversify PM by offering a general version and one like now dedicated for photos. I have seen a transition like that with the Norwegian DAM FotoWare. In the first decade of the 2000 it was just able to handle images and video with an add-in but after adapting it after the needs of the City Museum of Stockholm it now can handle all sorts of files including RAW, JPEG, DNG, TIFF and Office-files and other type of text files like PDF -files. It also indexes the content of the PDF-files which makes searches even more powerful than the possibilities the XMP itself normally offers.
As you can see in this example from the City Museum "Digitala Stadsmuseet" is able to handle both images and documents and museums publications - everything searchable in one single interface:
Here a few examples: (click the tabs)
A search that hits all types of material the museum handles: (It displays all sorts of documents and historical images over the very center of Stockholm - Hötorget)
https://digitalastadsmuseet.stockholm.se/fotoweb/archives/5000-Alla-fotografier/?q=H%C3%B6torgetMy point is: despite I´m not The City of Stockholm but just a user of PhotoMechanic with a need to handle my 70 000 images, I could also have a lot of use for a system that could handle all sorts of material instead of just images.
