PropertyGroup samples

Basics

From older OpenKM version we named "Metadata Groups" as "Property Groups".

Althought we understand this name not helps a lot to identifiying these methods with metadata ones, for historical reason, we continue mantaining the nomenclature.

For more information about Metadata.

On almost methods you'll see parameter named "nodeId". The value of this parameter can be a valid document, folder, mail or record UUID or path.

Example of nodeId:

  • Using UUID -> "f123a950-0329-4d62-8328-0ff500fd42db";
  • Using path -> "/okm:root/logo.png"

The class com.openkm.sdk4j.util.ISO8601 should be used to set and parse metadata date fields. The metadata field of type date values are stored into application in ISO-8601 basic format.

To convert retrieved metadata field of type date to a valid date use:

Calendar cal = ISO8601.parseBasic(metadataFieldValue);

To save date value into metadata field of type date use:

Calendar cal = Calendar.getInstance(); // Present date 
String metadataFieldValue = ISO8601.formatBasic(cal);
// metadataFieldValue can be saved into repository metadata field of type date

To add several values on a metadata field of type multiple like this:

<select label="Multiple" name="okp:consulting.multiple" type="multiple">
  <option label="One" value="one"/>
  <option label="Two" value="two"/>
  <option label="Three" value="three" />
</select>

            properties.put("okp:consulting.name", "new name");
            
            // Date fields must be saved with basic ISO 8601 format
            properties.put("okp:consulting.date", ISO8601.formatBasic(Calendar.getInstance()));
            ws.setPropertyGroupPropertiesSimple("/okm:root/logo.pdf","okg:consulting", properties);
