This demos starts at the myVocs homepage: http://myvocs.org.
The point of starting here is to approach use of the tools from the perspective of a current and active VO participant. While you may not be that kind of user today, you can quickly become that user.
In essence, this is the type of user most of us are today, when it comes to the Internet. If we are interested in finding something, we rarely expect to be able to browse to the data from a directory of Internet catagories, like we did in the early days of the Internet with Yahoo!. For a new Internet user that doesn't know what's out there, Yahoo!'s catagories are useful. For an experienced user, you just want the search bar. Google figured that out and simplied their UI accordingly. You go to Google's search site expecting to type in your search and access the content of interest by browsing off the results our your search command.
This brings us back to the initial myVocs page. This page is trimmed down to just the "search" box, only in the case of myVocs we can enter in more than just a search request. We can execute any defined command, giving us structured shortcuts to any destination.
The myVocs page diverges from the Google style slightly and does provide some hints as to where you can start. These example commands are a good place to start, so give it a try
- Type cms collabtools and press Enter
This is the "cms" command that takes one arguement that identifies the name of the VO your interested in. This command takes you to the cms tool for the VO which you identified.
