Downloading a pre-installed VM seems counter productive. Doing the whole process myself I have learned what is what and know where mistakes can take place. It seems that it is easier to trouble shoot when I download and build the machine myself. The building of the system does not take that much time and it adds ownership to the process.
On the other hand if you are working with lots of data taking the time to build the system may not be cost effective. If the system is already there then the people can concentrate on the repository. The collection can be up and available faster. Time can be better spent building collections instead of downloading and building virtual machines.
I enjoyed building the VMs and collections but I did not understand every aspect of the install so I am not sure it would be any advantage for me to build the VM instead of downloading one pre-installed.

Unit 11
Althought I could not get a theme loaded on my Omeka site I did like it the best. It seemed to be easier to navigate and the DC elements were very helpful and user friendly. The Omeka site was very helpful. The screencasts were very helpful and I liked seeing the actions before I did them. Reading the different forums gave me the insight into the way Omeka can be used and how libraries can use it.
As I remember DSpace was another site that was not hard to use. The way it linked pages to each other was a plus because it allowed for a stream of thought through the collecition. Drupal is similar to DSpace in that it has been around for a while and has more detail than Omeka. Jhove was very technical and it automated object ingestion, storage, access and preservation. It seemed that it was started and then forgotten as some of the information was outdated.
OAI-PMH was a little intimidating. I had trouble using it but it seems it would be a good tool in the Open Archive program. It seems as if I did not have enough background knowledge to use it effectively. I liked that it enhances access to e-prints archives.
Because all these different systems are open source their seervices are available to everyone. Each system has pluses and minuses but because they are open source you can decided which works best for your collection.

Unit 10
I searched the website Cyclades: An Open Collaborative Virtual Archive Environment. Its partners are the European Research Consortium for Informatics and Mathematics, the Institute of Computer Science, Fraunhofer FIT among others. It is a collaborative virtual archive service that has a core set of cross-archive value-added services. This allows for communication and collaboration between services.
I searched GEO-Leo which was a collection of earth science and mining related bibliographic records. There were some dead ends but most of the links worked and I got some good information from the collection. The collection by the German Research Association is offered to all German academics and scientists. It gives access to relevant books, journals and information resources.
I looked at Sheet Music Consortium. The members are UC Los Angeles, Indiana University, Johns Hopkins University, and Duke University. This is what I expect from a federated collection. The search was easy and I actually found the sheet music I was looking for. Some of the sheet music was not accessible because of copyright but all that I looked at were. Some of the searches took me to another site. “The Maine Music Box” where I was able to access the sheet music.
The last site I looked at was the Oaister site in the tech assignment. It was very large and well thought out. I was able to navigate through the different features with little trouble. Everything I clicked on had more things to click on. It has so many records and contributors that it might be overwhelming to some people.
I think a good federated collection has continuity and flow. The movement through the site must be fluid. The collection should be connected and well thought out. The collections I looked at were all at different levels of usability. I had a hard time finding anything in the first two sites I looked at. They seemed cumbersome and had a number of dead ends. The last two were much more successful. I don’t think the number of records or contributors is a negative for the Oiaster site because it is organized well and was easy to navigate. The sheet music site also had a large number of records but was not hard to navigante. I think the organization of the site is more important than the number of records it has.
