Dear All, I am now starting to work on a Vocabulary Editor specification that will allow external maintenance of Vocabulary Server content and have run into a design issue. Currently,there are two physically separate copies of the VS information repository. The master copy is as deeply buried behind security as possible. A second copy is more exposed and is served by the VS API. Two overnight crons run. The first brings versioning metadata of the master copy up to date. The second synchronises the web-exposed copy to the master copy.
This has a significant impact on the 'edit existing vocabulary' use case. The user downloads a copy of a vocabulary, edits it the uploads it. As it stands even if the changes made are instantly applied to the master copy they won't become web-visible until the following day. My question is simply 'Is this acceptable, if properly documented?'. If not, what is deemed an acceptable delay between upload and the uploaded version being available for download? Another related question is 'Can it be guaranteed that only one individual will drive the editor for a given content governance authority?' The answer ot this governs how much I need to worry about resolving multiple simultaneous changes and subsequent uploads to a single vocabulary. Cheers, Roy. >>> [EMAIL PROTECTED] 11/7/2008 3:53 pm >>> Hi Roy As requested, I've just created a very short draft specification for list governance at http://proj.badc.rl.ac.uk/ndg/wiki/NDG3/Vocab/HighLevelSpec Clearly we can work on it (expanding detail), but I think it's a relatively simple task, and should dovetail quite nicely with the spec required for the new API, which I would hope to support identically the same structure (i.e. we get something sensible back from an http GET on a sensible URI.
