PropertyGroup samples

Basics

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

Although we understand this name does not helps a lot to identifying these methods with metadata ones, for historical reason, we continue maintaining the nomenclature.

For more information about Metadata.

On most 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 metada field of type date to a valid date use:

DateTime date = ISO8601.parseBasic(metadataFieldValue);

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

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

setPropertyGroupPropertiesSimple

Description:

MethodReturn valuesDescription

setPropertyGroupPropertiesSimple(String nodeId, String grpName, Dictionary<String, String> properties)

void

Changes the metadata group values of a node.

The grpName should be a valid Metadata group name.

Is not mandatory to set into properties parameter all fields values, is enough with the fields you wish to change its values.

The sample below is based on this Metadata group definition:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE property-groups PUBLIC "-//OpenKM//DTD Property Groups 2.0//EN"
                                 "http://www.openkm.com/dtd/property-groups-2.0.dtd">
<property-groups>
  <property-group label="Consulting" name="okg:consulting">
    <input label="Name" type="text" name="okp:consulting.name"/>
    <input label="Date" type="date" name="okp:consulting.date" />
    <checkbox label="Important" name="okp:consulting.important"/>
    <textarea label="Comment" name="okp:consulting.comment"/>
  </property-group>
</property-groups>

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>

You should do: 

properties.Add("okp:consulting.multiple", "one;two");

 Where "one" and "two" are valid values and character ";" is used as separator.

            String username = "okmAdmin";
            String password = "admin";
            OKMWebservice ws = OKMWebservicesFactory.newInstance(host, username, password);
            
            try
            {
                Dictionary<String, String> properties = new  Dictionary<String, String>();
                properties.Add("okp:consulting.name", "new name");
                
	        //The date fields must be saved with basic ISO 8601 format
		properties.Add("okp:consulting.date", ISO8601.formatBasic(DateTime.Now));
	        ws.setPropertyGroupPropertiesSimple("/okm:root/logo.pdf","okg:consulting", properties);
            } 
            catch (Exception e)
            {

        }
    }
}
