It's alright :)

I would state it with the sentences switched:

if the application is executing the command "getPropertyValues", you
have to get meta-data from the CMIS service without downloading anything
expect the meta-data itself.

"getPropertyValues" is one of the commands to be first executed by the
application, usually to know if the content represents a folder or
a document.

in plural, even if it is only one property, you get a sequence.

Look at the API reference:
http://www.openoffice.org/api/docs/common/ref/com/sun/star/ucb/Command.html

long Handle;
contains an implementation specific handle for the command.=20

It is up to the implementation (that is, you) whether to use it or
simply ignore it. You can ignore it now and come back later.

> Also what is commandid? Any enumeration to represent various commandids?

For CommandId read
http://www.openoffice.org/api/docs/common/ref/com/sun/star/ucb/XCommandProc=
essor.html#execute
"is a unique id for the command. This identifier was obtained by calling
XCommandProcessor::createCommandIdentifier."

Most (if not all) implementations in the core code simply ignore this param=
eter.


Note that different css.ucb.Command's have different Command.Argument,
and XCommandProcessor.execute() returns different things. This is
document in the Dev's Guide, and with more detail in
http://www.openoffice.org/api/docs/common/ref/com/sun/star/ucb/Content.html
The SDK from trunk has a nicer formatted documentation.

For "getPropertyValues" you will have to implement a css::sdbc::XRow,
the internal helper implementation is ucbhelper::PropertyValueSet in=20
main/ucbhelper/inc/ucbhelper/propertyvalueset.hxx
main/ucbhelper/source/provider/propertyvalueset.cxx
