James,
There are a few options that will suit different use cases.
The XMP adaptation of VRA Core is fairly rich but may be overkill: http://metadatadeluxe.pbworks.com/w/page/73474265/VRA%20Panels%201_0%20Mapping
The newest IPTC Extension has artwork/object fields that, hopefully, will find their way into mainstream tools:
https://iptc.org/standards/photo-metadata/iptc-standard/
As Tony says, readability with common photo software is very important when publishing images to a general audience. For both of the above standards, there is a strategy to concatenate granular fields into the handful of fields that most software can read, typically Dublin Core. Our VRA group has created a guide for these fields based on testing several popular tools:
http://metadatadeluxe.pbworks.com/w/page/59200201/Basic%20artwork%20metadata%20guidelines
This list might a bit out dated, but it shows the results of our tests. It also has test images available for download (now login required):
http://metadatadeluxe.pbworks.com/w/page/47662311/Top%2010%20List%20of%20Embedded%20Metadata%20Properties
You can certainly use only these basic fields, but I would also consider using IPTC Extension or VRA so that, as the support of embedded metadata increases, your images will be more valuable. There is growing support for extracting structured metadata from images uploaded to online services, like shared databases and rights registries.

Hi James,
There isn't a standard as such, there are many options such as DC, VRA, IPTC, but for me the only one is IPTC because it is readable by common tools such as Adobe Bridge and many of the fields can be read by Windows Explorer and Apple Finder.
Digital Watermarking is dead in the water really, always was. Who was going to spend the legal resources taking someone on the other side of the world to court? (if you could find them in the first place)
In terms of standards in general, ISO is working on CH imaging standard which will aim to 'unify metrics, related methods, and tools used to specify and measure image quality capability of systems for the recording and evaluation of cultural heritage materials for archival purposes.’ You can read about it here.
http://www.imaging.org/ist/resources/standards/materials.cfm
You could speak to Richard Bayford, the IWM Photo studio manager for the current practise in the studio there.
Regards
Tony
