openCMIS: Get the information about the repository

openCMIS provides ‘RepositoryInfo’ class, it is used to get the information about the repository information.

By using RepositoryInfo instance, you can get following information.

a.   Repository id

b.   Repository name

c.    Description about the repository

d.   Vendor name

e.   Product name

f.     Product version

g.   Root folder id

h.   Repository Capabilities

i.     ACL capabilities

j.     Latest change log token

k.    CMIS version supported by this repository

l.     Get URL of a web interface for this repository

m. List of extension features etc.,

Following application prints basic information about the repository.
