| WAP Server |
A
frequently misused term. A WAP server by itself is really nothing more than a HTTP server
- ie. a web server. In order to confuse everyone, Nokia has a product which they call a
WAP server which is a WAP gateway and a HTTP server all in one. Ie. this is actually a
content providing servers and a gateway. The gateway takes care of the gateway stuff, and
the web server provides the contents. |
| WAP Gateway |
A WAP
gateway is a two-way device (as any gateway). Looking at if from the WAP device's side,
since a WAP device can only understand WML in its tokenized/compiled/binary format, the
function of the WAP gateway is to convert content into this format. Looking at it from the
HTTP server's side, the WAP gateway can provide additional information about the WAP
device through the HTTP headers, for instance the subscriber number of a WAP capable
cellular phone, its cell id and even things like location information (whenever that
becomes available). |
| WML Card |
A single
WML block of navigation and user interface in a WML deck. A WML card must exist inside a
WML deck containing one or more cards. WML decks are XML documents. |
| WML Deck |
A
collection of WML cards. The whole deck is loaded when the browser requests a URL, and
access to individual cards in the deck can be specified in the URL. |
| SGML |
Standardised
Generalised Markup Language. |
| UA |
User
Agent. Software that interprets WML, WMLScript, WTAI and other forms of code. |
| WMLScript |
Scripting
language for WAP devices. Based on JavaScript, but less powerful. |
| XML |
Extensible
Markup Language. W3C's standard for Internet Markup Languages. WML is one of these
languages. XML is a subset of SGML. |
| HDML |
Handheld
Markup Language |
| W3C |
World
Wide Web Consortium. http://www.w3c.org/ |
| WAE |
Wireless
Application Environment. (#NOK) The Wireless Application Environment specifies a
general-purpose application environment based fundamentally on World Wide Web technologies
and philosophies. WAE specifies an environment that allows operators and service providers
to build applications and services that can reach a wide variety of different platforms.
WAE is part of the Wireless Application Protocol. |
| WSP |
Wireless
Session Protocol. (#NOK) The Wireless Session Protocol provides the upper-level
application layer of WAP with a consistent interface for two session services. The first
is connection-mode service that operates above a transaction layer protocol, and the
second is a connectionless service that operates above a secure or non-secure datagram
transport service. |
| PDA |
Personal
Digital Assistant. Usually a hand-held device, such as the Palm Pilot. WAP isn't just for cellular phones. |
| Element |
An
element specify the markup and structural information in a WML deck. Some elements contain
a start and end tag such as the <p> and </p> tag, others are single elements
such as the <br/> tag. |
| DTD |
Document
Type Definition. (#NOK) The definition states which elements can be nested within others.
A DTD defines that the names and contents of all elements that are permissible in a
certain document, how often an element may appear, the order in which the elements must
appear, whether the start or end tag may be omitted, the contents of all elements, that
is, the names of the other generic identifiers that are allowed to appear inside them, the
attributes and their default values and the names of the reference symbols that may be
used. |
| WTP |
Wireless
Transaction Protocol |
| WTLS |
Wireless
Transport Layer Security. The "equivalent" to SSL (Secure Sockets Layer) widely
used in the HTML world - although not identical in functionality. |
| WDP |
Wireless
Datagram Protocol |
