There was a recent visit of Jens Klump and Lesley Wyborn to Lamont to work on IGSN members in June/July 2015.
The GFZ Handle Service used to be quite slow. The Smithsonian Institution was registering ~300,000+ samples by web services and it was very slow. Damian Ulbricht, Lulin Song, and DataCite worked together to improve the speed of the service - the speed is much improved now.
Geoscience Australia has registered about 2 million samples - the speed was very adequate. (after the fix)
Jens and others worked on the documentation, it needs a lot of work, it is in progress, there are many actions to complete. Information is spread over 4 different sites. Jens is working to consolidate all of the information onto GitHub, there will be an IGSN organization in GitHub. He is researching automatic ways to transfer the content.
Anthony Koppers: Is there a clear link from igsn.org to the GitHub page? JK: we will do that, the GitHub page is currently experimental. igsn.org will remain, but the wiki, trac ticketing system, and others will be consolidated.
Kerstin: With the expanding use of the IGSN we are increasing complexity of the use cases, we need to establish more guidelines. We should also discuss recent issues with IGSN syntax as an organization to make sure we are not diverging too much from what tools for IGSN are developed for. IGSNs are important for reproducibility, getting to metadata, and getting to the physical sample - IGSNs in publications should comply with certain rules.
Jens: we have the metadata working workshop where this can be discussed.
There will be a workshop next week, triggered by discussion in the iSamples Research Coordination Network (U.S. EarthCube project). There is a metadata working group from iSamples. One goal especially is to talk with the biological samples community. It is a working meeting to get metadata standards groups discussion on paper. There was a preliminary webinar:

Bernhard: will there be anyone representing the hydrologic community? Like CUAHSI? KL: yes, Gary Berg-Cross will be there.
Anthony K: are you planning to make this into a Standard with versions, etc.? KL: It is a good idea to pursue that path, it may be a long path. JK: I would like to define the metadata kernel but also discuss community practice extensions to the kernel at the workshop.
