What method do Planetary Scientists use for annotating and commenting images ? Is there a formal method in use or is this done informally using a graphics package to add text and markers ? The reason I ask is that I am trying to develop such a method for my project Space Data Wiki. The advantage to having a formal method is that the annotations can be linked using the "Semantic Web" using RDF and OWL technologies (as I understand it at the moment). See "Annotation". Any information or suggestions will be much appreciated.

Data is not annotations. Yes - there are huge amounts of data anticipated - of course there are - and of course I'm aware of that. That has NOTHING to do with annotating images. Nothing.

There are PDS conventions for describing data - as I am sure you are aware - but, I say again, annotations are massively diverse things from scales to grids to labels to arrows to paths to sites to directions to layers to bedforms to routes to dunes etc etc - and all of these are done by JPL, Cornell, ESA, ESOC, SWRI, ASU, CICLOPS, HRSC, MPI, dozens of institutions annotating thousands of things in a million different way - there can be no convention on how to do that. Even two people doing exactly the same thing, do it differently.

I would say you're looking for something that doesn't exist, and is impossible to establish. It's like trying to have one set of rules, for every sport in the world - from Football to F1. You need to better specify exactly what you mean by annotations before you can progress.
