The WebCGM XML Companion File (XCF) was added to WebCGM in the 2.0 version, and further enhanced in this 2.1 upgrade. The element and attribute definitions found in this section represent the WebCGM XCF DTD. This DTD may be extended by profiles deriving from WebCGM. The WebCGM XML companion files may be used for several purposes. There are many conceivable usage scenarios, but for the scope of WebCGM, the following four were identified as most important.
Scenario 1: A companion file can be used to bind application specific details (such as a part number) to a particular Application Structure. It is up to the application to control how the application-specific information is used.
Example 4.1: A companion file used to relate some application-specific data to graphical objects.
<!ENTITY % grobjectAttEXT "model:partNum CDATA #IMPLIED"
> <webcgm version="2.1" id="root-cgm"
filename="sample_1.cgm" xmlns:model="http://example.org"
xmlns="http://www.cgmopen.org/schema/webcgm/"> <grobject apsid="id_1"
model:partNum="bolt-100A"/> <grobject apsid="id_2"
model:partNum="wingnut-T9"/> ... <grobject apsid="id_49"
model:partNum="drill-bit-D01"/> <grobject apsid="id_50"
model:partNum="router-bit-B389"/> </webcgm> |
Scenario 2: A companion file could also be used to update a CGM illustration via the WebCGM DOM (see section Relationship with XML companion file for more information):
Example 4.2: A companion file used to update sample_2.cgm before being displayed by a user agent. Calls to some WebCGM DOM methods need to take place to perform this task.
<webcgm version="2.1" id="root-cgm"
filename="sample_2.cgm" <bindByName apstargetname="bolt_100"
screentip="Replacement part:bolt-100B"/> <bindByName apstargetname="wingnut_9"
screentip="Replacement part:wingnut-T9A"/> </webcgm> |
Scenario 3: Although it is out-of-scope of this version of the WebCGM XCF to fully mirror the hierarchical structure of a CGM graphic (see "Structure overview"), an XML Companion File could be used as a partial, scaled down XML inventory of a CGM illustration by enumerating the Application Structures IDs, types and (most) attributes.
Example 4.3: A companion file used as a partial inventory of sample_3.cgm. In this case, the description puts an emphasis on the hotspot region of each 'grobject' element.
<webcgm version="2.1" id="root-cgm"
filename="sample_3.cgm" <grobject apsid="id_1" region="1 0 0 100 100"/> <grobject apsid="id_2" region="1 200 0 300 100"/> ... <grobject apsid="id_49" region="1 1600 600 1700
700"/> <grobject apsid="id_50" region="1 1800 600 1900
700"/> </webcgm> |
This section and its subsections are normative, unless otherwise indicated.
It is not the intent of the WebCGM XML Companion File (XCF) to be a faithful XML representation of the object tree in a hierarchical WebCGM. Rather, XCF provides a mechanism to externalize both standardized and application (private) metadata from a structured WebCGM instance, and to bind it to the proper objects in the object tree of the WebCGM instance.
Accordingly, the structure of the XML Companion File is mostly flat. After
the root element, webcgm
, the various standard
XCF elements occur as siblings in the companion file (with the single
exception of linkuri
). So, for example,
grobjects
that have a parent-child relationship in the CGM are
siblings in the XCF. The normative WebCGM DTD for XCF expresses and enforces
this flat structure, independent of whatever hierarchy may exist in the
corresponding WebCGM instance.
Example 4.4: A mostly-flat companion file binds standardized metadata to a hierarchical object tree in a WebCGM instance.
<webcgm version="2.1" filename="sample_4.cgm" <grobject apsid="level-4-obj"
screentip="wingnut-400A"/> <grobject apsid="level-3-obj"
screentip="bolt-assembly-100A"/> </webcgm> |
|
Note: Example 4.4 uses a condensed schematic representation of the CGM code, eliminating numerous details in order to illustrate the point.
Example 4.4 illustrates another point about the relationship of the XCF contents to the corresponding WebCGM instance — the order of the XCF is not required to follow the order of the CGM contents.
As suggested by Example 4.4, the root element of a conforming XCF instance
must be the webcgm
element. The
webcgm
element corresponds to the Picture object in the CGM. See
Relationship with XML Companion
File for more discussion.
The next section deals in detail with application-specific metadata attributes and elements in an XCF. In order to unambiguously establish where in the WebCGM object tree those metadata are to be inserted, the application-specific attributes and elements (defined in a separate namespace) are placed in the XCF as attributes and child elements on standardized XCF elements that correspond (bind) to the appropriate object in the WebCGM. This is seen in example 4.1, for application-specific attributes. See also section Relationship with XML Companion File for more discussion.
The WebCGM DTD is extensible so that application-specific or industry-specific metadata may be added to the WebCGM object model (as shown in example 4.1). The extension definitions are implemented using namespaces. The DTD defines an extension entity for the content and attributes of most elements. As an example, a part manufacturer may want to associate parts information to graphical objects. This might be implemented with an extension that looks like:
<!ENTITY % grobjectAttEXT "model:partNum CDATA #IMPLIED" >
A host application could query the WebCGM DOM and retrieve the associated part information.
A set of rules must be followed when extending the WebCGM DTD:
The rules found above allow WebCGM user agents to process extended companion files in an interoperable manner.
The WebCGM namespace:
http://www.cgmopen.org/schema/webcgm/
Namespace example:
<webcgm version="2.1" filename="sample.cgm"
xmlns="http://www.cgmopen.org/schema/webcgm/">
Public Identifier for WebCGM 2.1:

System Identifier for the WebCGM 2.1:

DOCTYPE example. The following is an example document type declaration for a WebCGM XCF document:
<!DOCTYPE webcgm PUBLIC "-//

A file is a conforming WebCGM 2.1 XCF document if it adheres to the specifications described in this (WebCGM 2.1) document, including those in the WebCGM 2.1 XCF DTD, and in addition all of the following conditions are met:
webcgm
This section and its subsections are normative, unless otherwise indicated.
The standard XCF elements include:
webcgm
layer
, grobject
, para
,
subpara
bindById
and bindByName
.The standard XCF elements also include:
linkuri
. Linkuri is an APS Attribute, but is encoded as an
XCF element, rather than attribute, to avoid what would otherwise be an
overly complex encoding of the string that would comprise its value as an
XML attribute.For the standardized XCF content, most of the items expressed on XCF elements as XML attributes have a straightforward correlation to a standardized WebCGM attribute or property that may be set or inquired with a WebCGM DOMcall.
In general, the encoding of XML attributes on XCF elements is identical to the encoding of the corresponding parameters in DOM calls. For example, the WebCGMAppStructure interface (section 5.7.6) defines 'viewcontext' as a simple string of four numbers, whitespace separated (see Wsp definition, section 5.5). The encoding of 'viewcontext' as an XML attribute on any allowed XCF element is the same as its encoding as a DOM method parameter.
Similarly, the Style Properties (settable on the WebCGMPicture and WebCGMAppStructure interfaces), as XML attributes on the XCF elements have the same valid values and are encoded identically as in the corresponding DOM calls.
Geometric transform, which is DOM-settable (see WebCGMAppStructure) for APS of all types except 'grnode', is realized in XCF as XML attributes on the eligible XCF elements. They have the same valid values as the corresponding DOM attributes and parameters. However, the Float and WebCGMMatrix types of the DOM are encoded into a WebCGMString XCF attribute value as List-of-number subtype.
EXAMPLE. The parameters of DOM setTransform() are a matrix and a 'replace' flag. The matrix is represented by six numbers (a, b, c, d, e, f). In XCF, the value of the setTransform attribute would be a WebCGMString: "a b c d e f combine". For example, this would scale an object about the origin by 0.5 and translate it right by 0.1:
<grobject apsid=someAPS" setTransform="0.5 0 0 0.5 0.1 0 combine"
/>
CAVEAT! In XML, one cannot assume the order of attributes on an element. So for example, one cannot assume that two consecutive geometric transforms on a <grobject> element will be applied in the order written.
Flawed, order of application is not guaranteed:
<grobject apsid=someAPS" translate="0.5 0.1 replace" rotate="45 0 0 combine" />
Correct:
<grobject apsid=someAPS" translate="0.5 0.1 replace" />
<grobject apsid=someAPS" rotate="45 0 0 combine" />
The single exception to the use of consistent encodings is for the 'linkuri' APS attribute, which is encoded as an element in the XCF, for reasons as explained.
See the WebCGM DOM data types section for complete details.
Most of the XCF elements may have Style Properties as XML attributes (Style Properties are defined and supported on the DOM WebCGMPicture and WebCGMAppStructure interfaces.) The following entity definition is used in the DTD snippets of the subsequent subsections, on those elements which support Style Properties at both the APS level and Picture level. (The background-color Style Property that applies only at the Picture level.)
<!ENTITY % styleProperties "text-size CDATA #IMPLIED fill-color CDATA #IMPLIED intensity CDATA #IMPLIED stroke-color CDATA #IMPLIED stroke-weight CDATA #IMPLIED text-color CDATA #IMPLIED text-font CDATA #IMPLIED raster-intensity CDATA #IMPLIED stroke-type CDATA #IMPLIED stroke-offset CDATA #IMPLIED interior-style CDATA #IMPLIED hatch-index CDATA #IMPLIED pattern-index CDATA #IMPLIED edge-visibility CDATA #IMPLIED fill-offset CDATA #IMPLIED" > |
A single WebCGM XCF element must not contain both the intensity
property and one or more of the overlapping properties fill-color
,
stroke-color
, text-color
. Overlapping properties may
occur sequentially on different XCF elements, and then their processing is
defined by their order of occurrence (see Style Properties description).
See "Data types and encoding" for more about Style Properties.
Some of the XCF elements may have geometric transforms as XML attributes (geometric transform functionality is defined and supported on the DOM WebCGMAppStructure interface.) The following entity definition is used in the DTD snippets of the subsequent subsections, on those elements which support geometric transform.
<!ENTITY % geometricTransform "translate CDATA #IMPLIED rotate CDATA #IMPLIED scale CDATA #IMPLIED setTransform CDATA #IMPLIED" > |
A WebCGM companion file (or any other CGM profile derived from the WebCGM profile) must have a 'webcgm' element as the root element. The 'webcgm' element corresponds to the Picture node in the WebCGM DOM tree (see for example the WebCGMPicture interface in the DOM).
<!ENTITY % webcgmEXT "" > <!ENTITY % webcgmAttEXT "" > <!ELEMENT webcgm ( (layer | grobject | para | subpara | bindById | bindByName %webcgmEXT;)* ) > <!ATTLIST webcgm id ID #IMPLIED version CDATA #FIXED '2.1' filename CDATA #IMPLIED xmlns CDATA #FIXED "http://www.cgmopen.org/schema/webcgm/" background-color CDATA #IMPLIED pictureVisibility ( on | off) #IMPLIED %styleProperties; %webcgmAttEXT; > |
Attribute definitions:
id="xml:id"
Standard XML attribute for assigning a unique identifier to an element. Refer
to Extensible Markup Language (XML) 1.0 [XML10].
version="CDATA"
Represents the version of the WebCGM specification. The value is 2.1 for this
specification. Every conforming XCF must identify its version, either by
including this attribute on the webcgm element, or by including a DOCTYPE pointing to this WebCGM XCF's DTD, or both
(recommended). An industry-specific profile derived from this WebCGM XCF
specification must not use this attribute to identify its version, and should
define and require use of a namespace attribute to identify its profile
version. For example, if ASD includes in its future version of S1000D "n.m" an
XCF derived from WebCGM 2.1, the webcgm
tag might look like
this:
<webcgm version="2.1" asd:s1000d-version="n.m" xmlns:asd="http://example.org/asd/" ...>
filename="CDATA"
Represents the filename of the corresponding WebCGM file. 'filename' is a
descriptive attribute.
xmlns[:prefix]="CDATA"
Standard XML attribute whose value defines the "resource-name" for identifying
an XML namespace. Refer to Namespaces in XML. The 'xmlns'
attribute without prefix identifies the (default) WebCGM
namespace, and (with prefix) must be used to identify the foreign
namespace(s) of any application-specific metadata that
are used in the XCF instance. Note that the value given in the DTD snippet, and the attribute type (#FIXED),
apply only to the unprefixed, default WebCGM namespace.
<webcgm version="2.1" xmlns="http://www.cgmopen.org/schema/webcgm/" xmlns:asd="http://example.org/asd/" ...> <xcf:webcgm version="2.1" xmlns:asd="http://example.org/asd/" ...>
In the first example, the WebCGM namespace is declared as the default
namespace for the webcgm
element and its contents, and content in
the 'asd' namespace would use the "asd:" prefix. As the DTD shows, the second example is also valid
because the namespace IRI defaults properly
for the xmlns
attribute without prefix. It is recommended,
however, that the xmlns
attribute declaring the default (WebCGM)
namespace always be included.
background-color="CDATA"
background-color is a Style
Property for setting the background color of the Picture (root node of
WebCGM object tree).
pictureVisibility="on|off"
Defines the visibility for the picture that corresponds to the
webcgm
element of this XCF. This is similar to the 'visibility'
APS Attribute that can be applied to metafile Application Structures, except it
applies to the picture (on which the 'visibility' APS Attribute is not allowed
by CGM rules.) The effect is the same as the invocation of the
setPictureVisibility method on the WebCGMPicture interface of the DOM. .
styleProperties
