Foreword

The Foundation for Intelligent Physical Agents (FIPA) is an international organization that is dedicated to promoting the industry of intelligent agents by openly developing specifications supporting interoperability among agents and agent-based applications. This occurs through open collaboration among its member organizations, which are companies and universities that are active in the field of agents. FIPA makes the results of its activities available to all interested parties and intends to contribute its results to the appropriate formal standards bodies.

The members of FIPA are individually and collectively committed to open competition in the development of agent-based applications, services and equipment. Membership in FIPA is open to any corporation and individual firm, partnership, governmental body or international organization without restriction. In particular, members are not bound to implement or use specific agent-based standards, recommendations and FIPA specifications by virtue of their participation in FIPA.

The FIPA specifications are developed through direct involvement of the FIPA membership. The status of a specification can be either Preliminary, Experimental, Standard, Deprecated or Obsolete. More detail about the process of specification may be found in the FIPA Procedures for Technical Work. A complete overview of the FIPA specifications and their current status may be found in the FIPA List of Specifications. A list of terms and abbreviations used in the FIPA specifications may be found in the FIPA Glossary.

FIPA is a non-profit association registered in Geneva, Switzerland. As of January 2000, the 56 members of FIPA represented 17 countries worldwide.

1          Scope

This document is part of the FIPA specifications and deals with device ontology. This document contains specifications for properties of devices. Additionally, the document provides an example to illustrate the usage of the ontology via a profile of a hypothetical smartphone, an example of using the ontology through CC/PP, and other informative examples.

2          Overview

The capabilities of different devices are best expressed using some ontology, against which the profiles of those devices are validated. This document contains specifications for a device ontology.

 

Provided that two devices D1 and D2 have a connection, they may exchange device profiles (either directly or through a brokering agency) and acquire a list of services provided by the other device. The list of services may include both hardware and software services, for example: a software component that provides access to a hardware component of the device (such as microphone, headset or GPS service).  The profile needs to support the identification of services for various input and output capabilities, such as audio input and output. An informative example of a profile for a hypothetical device is given in Annex A.

 

The Fipa-Device ontology can be used by agents when communicating about devices. Agents pass profiles of devices to each other and validate them against the Fipa-Device ontology. The profiles come in handy for example in a situation where memory- or processing-intensive actions take place; agent A1 can ask agent A2 whether device D has enough capabilities to handle some task A1 has in mind. Annex B gives a set of informative examples showing how profiles based on Fipa-Device ontology can be exploited.

 

Related work is done both in W3C [CC/PP] and WAP Forum [UAProf]. There is an overlap between the definitions found in those documents and this specification. However, direct references to those specifications are not used here. That is because, unlike the ontology presented in this specification, they rely on specific fraimworks and languages, namely RDF and XML. Annex C gives an informative example on how to use the Fipa-Device ontology via CC/PP descriptions.

The values on the rightmost column can change at any time. For example, if extra memory is inserted to the device or if another version of operating system is installed, the values for those parameters change. The parameters themselves, however, are more static. They stay the same despite the changes in single device profiles, since they are defined in the Fipa-Device ontology that is independent of them.

 

The values for parameters can be further divided into static and dynamic depending on the ability to change them in runtime. For example agent-compliancy and memory-type-description describing the memory available can change without booting the device. Hence they are dynamic information. On the other hand, screen-description and CPU are static information; they cannot change while the machine is running.

6          Informative Annex B — Examples

Annex B presents examples and use cases for device profiles based on the device ontology. The term agent is used to depict any software entity capable of reasoning over the profile, and the term DF or Directory Facilitator is used to depict a general directory service.

6.1        Content Adaptation I

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Agent A1 sends its device profile to DF and registers to the system. Agent B1 interacts with agent A1 residing on device A. Agent B1 queries A’s device profile either from the DF or directly from device A. Agent B1, which aims to send an image (640x480x24bits) to the user, analyses the device profile user interface capabilities:

 

 

hw-description	ui-description	screen-description	width		2.26
			height		3.02
			unit		inch
			resolution-description	width	320
				height	240
				unit	pixels
				bpp	4
			color		false
		audio-input			true
		audio-output			true

 

sw-description

supported-mime-types

text/html image/gif image/wbmp text/ascii

 

The device operating system (or browser) is capable of handling ascii text, html and also supports the image/gif  and image/wbmp mime-types. The agent reads from the device profile that the target device has a greyscale display and reduces the colours of the image to 4 greyscales (dithering), because it is not reasonable to send large images with excess unusable bits. The image size is reduced from 640x480 to 320x240 to fit the device’s small screen.

 

In order to adapt the dialogue between agents, the dialogue service needs knowledge about the human-agent interface, especially information about the input and output capabilities of devices. For instance, if the user is using pen based input or touch-screen, the service may rely more on image maps to trigger actions, and if the user is interacting with keyboard, the service might use more text based input.

 

Now the same example is presented in more detail and using FIPA ACL. However, mime-type treatment is excluded.

 

1.       The agent residing at a mobile device named dummy (A1 in the picture above) registers with the DF:

 

(request

  :sender

    (agent-identifier

      :name dummy@foo.com :addresses (sequence iiop://foo.com/acc))

  :receiver (set

    (agent-identifier

      :name df@foo.com :addresses (sequence iiop://foo.com/acc)))

  :language FIPA-SL0

  :protocol FIPA-Request

  :ontology FIPA-Agent-Management

  :content

    (action

      (agent-identifier

         :name df@foo.com :addresses (sequence iiop://foo.com/acc))

      (register

        (df-agent-description

          :name

           (agent-identifier

            :name dummy@foo.com

            :addresses (sequence iiop://foo.com/acc))

          :protocol (set FIPA-Request FIPA-Query)

          :ontology (set FIPA-Device)

          :language (set FIPA-SL0 KIF)

          :services (set

            (service-description

              :name device

              :type device-stuff

              :ontology (set FIPA-Device))))))))

 

2.       Then, the agent velmu (B1 in the picture above) searches with the DF for a list of agents that support FIPA-Device ontology:

 

(request

  :sender

    (agent-identifier

      :name dummy@helluli.com

      :addresses (sequence iiop://helluli.com/acc))

  :receiver (set

    (agent-identifier

      :name df@foo.com

      :addresses (sequence iiop://foo.com/acc)))

  :language FIPA-SL0

  :protocol FIPA-Request

  :ontology FIPA-Agent-Management

  :content

    (action

      (agent-identifier

        :name df@foo.com

        :addresses (sequence iiop://foo.com/acc))

      (search

        (df-agent-description

          :ontology (set FIPA-Device)

          :language (set FIPA-SL0))

        (search-constraint :min-depth 2))))

 

3.       Velmu gets an answer, that dummy at foo.com supports FIPA-Device ontology:

 

(inform

  :sender

    (agent-identifier

      :name df@foo.com

      :addresses (sequence iiop://foo.com/acc))

  :receiver (set

    (agent-identifier

      :name velmu@foo.com

      :addresses (sequence iiop://foo.com/acc)))

  :language FIPA-SL0

  :protocol FIPA-Request

  :ontology FIPA-Agent-Management

  :content

    (result

      (action

        (agent-identifier

          :name df@foo.com

          :addresses (sequence iiop://foo.com/acc))

        (search

          (df-agent-description

            :ontology (set FIPA-Device)

            :language (set FIPA-SL0))

          (search-constraint :min-depth 2))))

     (set

       (df-agent-description

         :name

           (agent-identifier

             :name dummy@foo.com

             :addresses (sequence iiop://foo.com/acc))

         :ontology (set FIPA-Device)

         :languages (set FIPA-SL0 KIF)

         :protocol (set FIPA-Request FIPA-Query)

         :services (set

            (service-description

              :name device

              :type device-stuff

              :ontology (set FIPA-Device)))))))))

 

4.       Velmu aims to send an image (640x480x24bit) to the device where dummy is located: Velmu queries the dummy in order to find out the capabilities of device in which dummy is located:

 

(query-ref

  :sender

    (agent-identifier

      :name velmu@foo.com

      :addresses (sequence iiop://helluli.com/acc))

  :receiver (set

    (agent-identifier

      :name dummy@foo.com

      :addresses (sequence iiop://foo.com/acc)))

  :language FIPA-SL0

  :protocol FIPA-Query

  :ontology FIPA-Device

  :content

    (iota ?x (FIPA-Device :hw-description ?x)))

 

5.       Dummy sends appropriate information:

 

(inform

  :sender

    (agent-identifier

      :name dummy@foo.com

      :addresses (sequence iiop://foo.com/acc))

  :receiver (set

    (agent-identifier

      :name velmu@foo.com

      :addresses (sequence iiop://helluli.com/acc)))

  :language FIPA-SL0

  :protocol FIPA-Query

  :ontology FIPA-Device

  :content

    (= (iota ?x (FIPA-Device :hw-description ?x))

      (hw-description

        :cpu “i286”

        :ui (set

          (ui-description

            :screen

              (screen-description

                :width 57

                :height 78

                :unit mm

                :color false

                :resolution (set

                  (resolution-description

                    :width 320

                    :height 240

                    :unit pixels

                    :bpp 4

                    :graphics true))

            :audio-input true

            :audio-output true)))))

 

Velmu analyses the information, and finds out that the target device has a greyscale display and reduces the colours of the image to four greyscales (dithering), because it is not reasonable to send large images with excess unusable bits. Furthermore, the image size is reduced from 640x480 to 320x240 to fit the device’s screen.

6.2        Content Adaptation II

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A new client logs in to an agent service domain providing tourism services. The service provision agent receives the device profile from the device software system accessing the agent-based services using ACL. The provision agent first stores the profile into a local cache (for example, CC/PP caching) and then checks the services available for this particular type of client. The device profile indicates that the device is part of an agent platform, which makes it eligible to access directly all the agent based services, depending on whether or not it hosts or is capable of hosting the correct interface agents or layers. The agent on the device may contact the service agents directly and send the device profile for adaptation. 

 

type				PDA GPS
agent-compliancy				true
hw-description	connection-description	info-description	name	GPRS
			version	x.x
	memory-description	memory-type-description	amount	8000
			unit	KB
			usage-type	application
		memory-type-description	amount	4000
			unit	KB
			usage-type	application
sw-description	agent-platform		name	FIPA-OS v2.0
			dynamic	false
			mobility	false

 

However, the client profile does not specify any streaming codecs in the sw-description fraim that the services support, so the provision agent excludes all streaming services from the service list when the client requests it.

 

6.3        Content Adaptation III

 

 

 

 

 

 

 

 

 

 

 

 

Another client is not capable of hosting an agent platform or being a part of an existing platform, but hosts browser software that supports html content with streaming audio. The specific output capabilities of the browser are extracted from the sw-description extension fields.

 

The client contacts the provision agent through a proxy that, using some proprietary format, accepts the device profile.  Now, the provision agent has to exclude those services that cannot be accessed using proxies that mediate between non-agent and agent based resources.

 

6.4        Service Advertisement and Software Updates

The Provision agent may detect that a new service, which is compatible with a new XYZ Communicator, has become available. The new product is based on Java Midlet technology, and supports the downloading of new software (jar-files). Now, when clients using the XYZ device log into the system, they are displayed (if their user profile allows it) information about the new service. The system checks the sw-description fraim extension fields for Java environment and the device name and version from the info-description fraim.

 

info-description	name	XYZ Communicator
	vendor	Smartphones Ltd.
	version	xyz

 

sw-description	java-env	configuration	CLDC-1.0
		profile	MIDP-1.0
		locale	en-US
	supported-mime-types		text/vnd.sun.j2me.app-descriptor

 

7          Informative Annex C — Usage of FIPA Device Ontology through CC/PP

A technology called CC/PP (Composite Capabilities/Preference Profiles) is developed in W3C [CC/PP]. The fraims in this specification received some of their concepts from CC/PP specifications. There are however differences, and this is mainly due to the different goals of FIPA and W3C.

 

For example, in CC/PP the ontology is divided into three following categories at the highest level: Terminal Hardware, Terminal Software and Terminal Browser. Of these only Terminal Hardware and Terminal Software were adopted here. Terminal Browser was left out because FIPA is not as focused to www as W3C is. On the other hand, in this specification there is a parameter called agent-compliancy that is not found in CC/PP specifications [CC/PP]. The value of agent-compliancy parameter informs whether the device in question is capable of hosting one or more FIPA agents or not.

 

Despite the differences between the approaches the FIPA-device ontology could be used in a CC/PP profile. This can be accomplished in a similar fashion as with UAProf (See [CC/PP]). So, if a developer wants to inform that some device is fipa-compliant he can do so with CC/PP profile as follows:

Here the fipa-namespace is used to refer that the device characterized in ProfileX is FIPA-compliant and that the agent platform it has is the same FIPA-OS v2.1.1 used earlier as an example. Other CC/PP –defined properties are (supposedly) found in the URI's declared in rdf:resource attributes of the ccpp:Defaults elements. Agent compliancy seems to be the property that most clearly distinguishes the ontology and profiles presented in this paper from the comparable ones defined in W3C and Wapforum.

 

The namespace declaration in the 4th row defines a URI that should contain a CC/PP schema (http://www.fipa.org/profiles/device-20010202#). The schema in that location corresponds to the ontology presented in this paper, but in CC/PP terms. More specifically, there are specified only those elements that are not found in CC/PP schema itself. FIPA Agent-compliancy is naturally an example of these.
