path in alfresco

[anshul]

Hi
I am new to alfresco and i am required to create a webservice for creating content in alfresco. I was going through an example code and i came across this line
/app:company_home
can any body please tell me what does this '/app' means and please explain me in detail the path structure in alfresco

Thanks

Names for paths, properties and aspects in alfresco have a namespace as well as a local name. 

By convention namespaces follow the internet  and XML standards such as http://www.alfresco.org/model/application/1.0 and are enclosed in braces e.g. {http://www.alfresco.org/model/application/1.0}   however that's a bit long winded to type so you can also use a shorter "namespace prefix" in this case "app:"

So in the example your code is trying to find the node with the path / app:company_home
