How to trust the persistence of GUIDs

After some rather quiet months, members of the Taxonomic Database Working Group (TDWG) have started to discuss the GUID (LSID) issue again.
Beneath the never ending discussion on which identifier system (DOI, LSID, PURL, handle etc.) is best, some other interesting issues have been raised: does a GUID system need central services, does it need a business model (money) etc.

Most interesting Roger Hyam has questioned the trustworthiness, thus persistence of GUIDs. He comments:

What I find most interesting is that the only people who promise persistence are people who are trying to persuade you to use their system. The basic message is “don’t trust them trust us”
....
When we say GUID persistence what we really mean is reliability of GUID resolution in the short term. This is something entirely different from persistence for the long term! If it doesn’t work now we will never build a system that is worth preserving into the future. Lets just do the easy stuff now and then migrate it if we ever need to. I believe this is my final word on persistence of GUIDs

Good point! But instead of questioning the trustworthiness of GUIDs in general we should start thinking on ways to ensure or at least enhance it. So, how can we REALLY trust? Surely not based on promises. But based on facts!

Therefore, the only way such service providers (also archives, databases etc.) could prove their trustworthiness would be a specific audit procedure and certificates.

There are some initiatives working on this. For example the German nestor group. They developed a criteria catalogue for long term archives largely based on the OAIS model. Another check list is the TRAC list here. And there is the European DRAMBORA project which provides a repository audit method based on risk assessment'.

The TDWG GUID group was focusing on technology, which was good to demonstrate a GUID system can work for biodiversity informatics. Now that we face these 'new' problems with GUIDs (business model + trustworthiness) TDWG should continue, revitalize the GUID group and care about these issues.

A good starting point would be to develop such an audit procedure for LSIDs, based on the models mentioned above. TDWG (or some other organisation) could offer these audits and LSID authorities could get certified. This would enable them to demonstrate their trustworthiness, thus the persistence of their GUIDs. Such a certificate could electronically be assigned and added for example as a link to the LSID metadata.
And why offering such audits for free? Maybe revenues from audit certificates could be one pillar of a future business model for LSIDs .. or TDWG?

A preprint archive for the geosciences

Today two interesting blog posts about getting hold of geoscientific papers have been published: The Open Source Paleontologist lists several ways to find and retrieve pdfs on your own. Dave Hone picks this up and complains a bit about those people who are too lazy to use these resources but are asking copies directly from the authors-thus causing extra work.

Surely, there are a variety of possibilities to find relevant literature on the web. But the majority of geoscientific papers are still published in commercial, closed access journals. So even if you found your artcle on Google Scholar, you'll frequently end on a page asking you for your credit card, unless you work for an institution which can afford the necessary licenses or it was publishe in an Open Access journal.

Open Access is a fine thing and many interesting papers already appear in open access journals such as PLOS. The idea certainly will become even more popular in the future. But in my opinion it is unrealistic to assume that researchers will favor open access journals for their top results when they have the chance to get their 'Nature paper'.
Other disciplines have reacted on this dilemma and provide and maintain so called preprint archives such as Arxiv. A preprint is a draft of a scientific paper that has not yet been published in a scientific journal. Preprint archives enable authors to quickly circulate their results and most important: copies of archived preprints are freely available!

Unfortunately, there is no dedicated geoscientific preprint archive :(( You can find geoscientific preprints in some institutional repositories and postprints on some homepages etc.., but there is no common access point.

But it should be there! Could a geo preprint archive be a community effort? Of cource it had to include the community, but could a community driven archive work?
Alternatively, libraries could take on that responsibility. So... geolibrarians could you hear me? Give us a working geo preprint archive, ..please.. (maybe you could call it Geoxiv;) ).
Sure, motivating the geo community to contribute will not be an easy job, but maybe one just has to start?
