CMIS: property types

Cmis specification define 8 types.

a.   boolean

b.   id

c.    integer

d.   datetime

e.   decimal

f.     html

g.   string

h.   uri

'org.apache.chemistry.opencmis.commons.enums.PropertyType' enum defined above property types.

For single valued String, Id and HTML properties, a repository MAY support the distinction between a set value with an empty string (length = 0), and a "not set" value. In this case an empty value element (e.g.<cmis:value/>) inside of a property element will indicate a "set but empty" string property. A property element without a <cmis:value/> will indicate a property in a "not set" state.

id property

'id' represents a random string used to uniquely identify a cmis object. You can only use 'id' property in "equal" or a "not equal" comparison with a string literal or with another id.

html property

'html' property is used to hold the document or fragment of Hypertext Markup Language (HTML) content.

Following application print all the properties (displayname, type and value) of the root folder.
