PropertyGroup samples

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 metadata 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

Suggested code sample

First, you must create the webservice object:

OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

Then should login using the method "login". You can access the "login" method from webservice object "ws" as is shown below:

ws.login(user, password);

Once you are logged with the webservices the session is keep in the webservice Object. Then you can use the other API methods.

At this point you can use all the Property Group methods from "propertyGroup" class as is shown below:

ws.propertyGroup.addPropertyGroup("8cd1e072-8595-4dd3-b121-41d622c43f08", "okg:consulting", propertiesMap);

Methods

addPropertyGroup

Description:

MethodReturn valuesDescription

addPropertyGroup(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:

Gson gson = new Gson();
List<String> values = new ArrayList<>();
values.add("one");
values.add("two");
properties.put("okp:consulting.multiple", gson.toJson(values));

Example:

package com.openkm;

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

import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.impl.OKMWebservices;

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

        }
    }
}

Before changing metadata, you should have the group added in the node ( see addGroup method ) otherwise will be raised and error.

It is not mandatory to set in the properties parameterMap 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">

    <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.

Another option:

Gson gson = new Gson();
List<String> values = new ArrayList<>();
values.add("one");
values.add("two");
properties.put("okp:consulting.multiple", gson.toJson(values));

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> properties = new HashMap<>();
            properties.put("okp:consulting.name", "set name");
            // Date fields must be saved with basic ISO 8601 format
            properties.put("okp:consulting.date", ISO8601.formatBasic(Calendar.getInstance()));
            properties.put("okp:consulting.comment", "set comment");

            ws.propertyGroup.setPropertyGroupProperties("8cd1e072-8595-4dd3-b121-41d622c43f08", "okg:consulting", properties);
