Property Groups

This is easy and powerful for building custom properties. You can user this feature to add information to documents. For example, if you store the invoices in a folder you can add a property group to set the client name and the quantity. You will see this important data without opening the documents. Also you can search by these custom properties later.

You need to create some file, for example PropertyGroup.cnd and insert some values in other two files PropertyGroupBundle.properties and PropertyGroupValues.properties.

• $JBOSS_HOME/PropertyGroup.cnd
• $JBOSS_HOME/PropertyGroupBundle.properties
• $JBOSS_HOME/PropertyGroupValues.properties

To try this test login as okmAdmin and go to Administration → Utilities → Register property groups. Set full path with the location of the local file PropertyGroup.cnd and push the register button. The properties will be registered.

REGISTERED GROUPS CANNOT NOT BE UNREGISTERED. They can always be updated but they cannot be deleted after registration !!! Try it out on a test installation first.

About files:

• PropertyGroup.cnd: There are general definitions on each parameter (for example the parameter okp:technology.type)

<okm = 'http://www.openkm.org/1.0'>
<okg = 'http://www.openkm.org/group/1.0'>
<okp = 'http://www.openkm.org/group/property/1.0'>

- okp:technology.language (string) = '' autocreated
- okp:technology.description (string) = '' autocreated
- okp:technology.comment (string) = '' autocreated

[okg:consulting] mixin

okp\:technology.type=4,one,two,three

OpenKM tries to find the correct language in your property files. If it does not exist uses it uses PropertyBundle.properties.

The users can assign a property group to a document using these toolbar buttons:

• Add property group →
• Remove property group →

And the properties will be shown in the information area. You can edit the values of the properties using the Change button. Then you can change these values. Also can remove a property group from a document by clicking the Delete button.
