Workflow

[Anita Richards]

... or Registry?

This is a more general point on authinetication.  THere are (at least) two
main categories

1) Data are restricted by date.  Typically, a data set will be restricted
to a specific list of named individuals for 1 yr, then open to all.  This
seems to me to be a relatively easy case, as long as the data ptovider
specifies the correct date and list of people.  Howver we would need a few
standard elements for these terms

2) Data which are available only to people working in certain countries or
institutes or even of certain nationalities (with or without a cut-off
date).  This seems a far more complicated case and maybe should be left on
one side unless that is the specific situation which Elizabeth's science
case produces.

As a further complication, data might be in a catalogue (e.g. an observing
log) which is parly public and partly restricted.  Do we need to ask data
providers to produce separate catalogues/archives? To conform to a
standard code for identifying public and private parts?

In the radio archive context, we will have to tackle some of these issues
in the next year or so and I thnk that some standards are needed.  However
to me it seems more a Registry problem than a workflow problem, except
that there would need to be some way of passing the identity of the user
to a data provider, to decide whether to respond to a query.
