Hi, An Australian group called TPAC (Tasmanian Partnership of Advanced Computing) has sponsored the development of a digital library portal which is capable of crawling over OpenDAP networks, extracting the metadata vis the DAS and building up a searchable digital library of data. I found this out at the APAC conference, at which I presented a paper on the capacities of OpenDAP for linking institutions and making a consistent interface between them. There are some strong synergies between the TPAC digital library software and what OpenDAP represents at a lower level. Hopefully, we will be setting up this software on a research box here at the Bureau, and I'll let you know if it lives up to expectations. Cheers, -Tennessee
