Glossary

adapter

A dynamically loaded Java class that acquires content from an external source, such as a Web site or a database, and converts the content into Mobile XML. Pre-built adapters include the Web Integration adapter, SQL adapter, and Strip adapter.

Adapter Result format

A general, user interface-independent content format. Content in Adapter Result format requires conversion to Simple Result format before it can be converted to the final target format.

bookmark

A link from a service to an external, device-compatible data source that does not require Wireless processing.

core

The Wireless component that manages the Wireless repository and service requests.

daemon

A background process that performs a specified operation in response to certain events or at specified times.

device portal

The interface where mobile device users access their Wireless services.

device transformer

A transformer that converts content from Simple Result format into the target format.

DOM Interface

Document Object Model. The interface that allows programs and scripts to access and transform processed XML documents.

DTD

Document Type Definition. A file in an XML document that defines how the application presenting the document should interpret the XML document.

end user

A person who accesses a Wireless service from a client device.

filtering

The process of transforming content by replacing existing markup tags with tags that represent another format.

HDML

Handheld Device Markup Language. A reduced version of HTML designed to enable wireless pagers, cellular phones, and other handheld devices to access Web page content.

IMAP

Interactive Mail Access Protocol. A hierarchical mail storage and retrieval structure.

HTML

HyperText Markup Language. The document format that defines the page layout, fonts, and graphic elements, as well as the hypertext links to other documents on the Web.

JNDI

Java Naming and Directory Inerface. A set of APIs that provide directory and naming functionality to Java applications.

JSP

JavaServer Pages. A technology based on Java servlets which separates the functions of Web page layout and content generation. JavaServer Pages technology enables the creation of server-generated Web pages incorporating dynamic content.

LDAP

Lightweight Directory Access Protocol. Protocols for accessing directories. The LDAP protocols support TCP/IP.

logical device

An object that describes either a physical device, such as a cellular phone, or an application, such as email. There is a default device transformer for each logical device.

master service

The core implementation of a service. The master service object invokes a specific adapter, and identifies the transformer used to convert content for the target device.

MIME

Multipurpose Internet Mail Extensions. A mail type that defines the message structure for different 8-bit character sets and multi-part messages.

Mobile XML

A set of DTDs and XML document conventions used by the Wireless to define content and internal objects.

Personalization Portal

A Web-based interface that end users access to select services and configure their device portal. Users access the Personalization Portal from their desktop computers.

private service tree

A service tree that is owned by a specific end user.

provisioning adapter

The adapter used to create, modify, and delete user objects in the Wireless repository.

public service tree

A service tree that is owned by the Wireless system, and can be accessed by any end-user.

repository

An Oracle8i database which stores all of the Wireless objects, such as users, groups, adapters, and services.

request

A query to initiate a desired Wireless service. Requests are submitted on behalf of end-users to the Wireless server.

request manager

The Wireless component that processes requests for services. The request manager authenticates the user, submits the request to the Wireless core, and retrieves the device type and any presentation settings. The request manager also forwards converted content from the transformer to the user.

request object

An XML document representing a request for service.

result transformer

A transformer that converts content from Adapter Result format into Simple Result format.

RMI

Remote Method Invocation. A standard for creating and calling remote objects. RMI allows Java components stored in a network to be run remotely.

sample repository

The initial Wireless repository, which includes pre-built objects such as transformers, adapters, and logical devices.

service

A core object used in a Wireless server to represent a unit of information requested by, and delivered to, a Wireless client. An end user typically sees a service as a menu item on a device or as a link on a Web page.

service alias

A pointer to a master service. When a service alias is placed in a service tree, the corresponding service becomes available to the owner or owners of the service tree.

service designer

The visual interface for creating and managing Wireless users, user groups, adapters, transformers, and services.

service tree

A tree data structure containing one or more services. Service trees make services available to end users.

Simple Result format

A content format that contains abstract user interface elements such as text items, menus, forms, and tables.

source format

The original format of content retrieved from an external data source by a Wireless adapter. For example, the source format of Web page content is HTML.

Strip adapter

An adapter that retrieves and adapts Web content dynamically.

strip level

The class used by the strip adapter to process markup tags in source content.

SQL adapter

An adapter that retrieves and adapts content from any JDBC-enabled data source.

stylesheet

An XSLT (eXtensible Stylesheet Language Transformations) instance that implements content presentation for XML documents. Wireless transformers can be either XSLT stylesheets or Java programs.

target format

The format required to deliver data to a specific type of client device.

Thin HTML

A minimal version of HTML implemented by a transformer in the starter Wireless repository. Thin HTML does not include support for frames, JavaScript, or other advanced features.

transformer

A Wireless object that converts content returned by the Wireless adapters. Result transformers convert Adapter Result documents into Simple Result documents. Device transformers convert Simple Result documents into the target format.

TTML

Tagged Text Mark-up Language. A lightweight version of HTML suitable for most PDAs.

user agent

An object that associates an end user with a device type.

user group

A Wireless object that represents a set of users that are grouped together based on common criteria such as interests, subscription level, or geographic location.

VoxML

A markup language that enables the use of voice to interface with applications.

WAP

Wireless Application Protocol. A wireless standard from Motorola, Ericsson, and Nokia for providing cellular phones with access to email and text-based Web pages. WAP uses Wireless Markup Language (WML).

Web Integration adapter

An adapter that retrieves and adapts Web content using WIDL files to map the source content to Wireless XML.

WIDL

Web Interface Definition Language. A meta-data language that defines interfaces to Web-based data and services. WIDL enables automatic and structured Web access by compatible applications.
