Basics

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

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

For more information about Metadata.

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

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

Calendar cal = ISO8601.parseBasic(metadataFieldValue);

To save the date value in the 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

Methods

addGroup

Description:

MethodReturn valuesDescription

addGroup(String uuid, String grpName, Map<String, String> propertiesMap)

void

Adds an empty metadata group to a node.

The grpName should be a valid Metadata group name.

It is not mandatory to set in the propertiesMap 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.put("okp:consulting.multiple", "one;two");

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

Example:

package com.openkm;

import java.util.Calendar;
import java.util.HashMap;
import java.util.Map;

import com.openkm.sdk4j.OKMWebservices;
import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.util.ISO8601;

public class Test {

    public static void main(String[] args) {
        String host = "http://localhost:8080/openkm";
        String user = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(user, password);
            Map<String, String> propertiesMap = new HashMap<>();
            propertiesMap.put("okp:consulting.name", "new name");
            // Date fields must be saved with basic ISO 8601 format
            propertiesMap.put("okp:consulting.date", ISO8601.formatBasic(Calendar.getInstance()));
            propertiesMap.put("okp:consulting.comment", "new comment");

            ws.addGroup("8cd1e072-8595-4dd3-b121-41d622c43f08", "okg:consulting", propertiesMap);
        } catch (Exception e) {

        }
    }
}

removeGroup
