Publishing new vocabularies - which resolver service

I hope this is an appropriate forum to ask advice.

We have been using the purl.org resolver service for some years to provide
a globally unique, persistent, resolvable identifier for Australian
research grants so they can be used in metadata describing research outputs
like publications, data, software etc. They resolve currently to a view
page in Research Data Australia - researchdata.ands.org.au. There is an API
but it returns only JSON currently, not XML or RDF

We decided not to run our own resolver service because we are not an
ongoing organisation with a guaranteed persistent domain and felt that a
public resolver service was more suitable. At the time purl.org seemed the
right choice. We are now struggling because we cannot make any changes. As
has been noted in this forum the admin UI is not available at the
moment. We also were concerned when the ability to create our own
sub-domain was removed as we envisage want to hand over some sub-domains
from our root, *au-research, *to different parties for maintenance.

We now also support the Vocabularies Australia Service
http://ands.org.au/online-services/research-vocabularies-australia using
the SISSVoc software which was established to assist with the publication
and widespread use of scientific vocabularies.

The ANZSRC Field of Research Vocabulary (ABS 1297.0) which is used to
classify research and its outputs in Australian and New Zealand is also
published through this service and we maintain purls for these vocabulary
terms eg

http://purl.org/au-research/vocabulary/anzsrc-for/2008/

We want to extend this provision of PURLs to other vocabularies but we
cannot use the sane purl domain because of the current problems with OCLC
supported purl.org service

We need to decide whether to -

   - switch to w3id.org as the domain for the other vocabulary purls
   - run our own resolver service under a domain name we think can be
   transferred to another organisation if/when necessary
   - look for another public resolver service
   - be patient and wait for the situation with purl.org to resolve itself
   (no pun intended)
