1. Introduction

1.1 Overview

This document describes the XML binding for the IMS Content Packaging v1.1.4 specification. This document specifies the binding of the Content Packaging specification in the W3C XML 1.0 Specification.

There are some specific rules that have guided the creation of this XML binding document:

  • The XML binding will adhere to the XML 1.0 Specification of the W3C;
  • It must maintain the definitional structure of the specification;
  • It must permit extensions.
  • The latest agreed practice within IMS is that camel case is used for the element tags in XML. This has not been adopted in this maintenance release because this would have required all previously created content package manifests to be altered. Instances that conform to CPv1.1.3 are compatible with CPv1.1.4 (with the exception of changing the XSD control document assignment in the header of the instance file). Instances that may not conform are those that have an <organization> element with 0 <item> elements.

1.2 Scope and Context

This document is the IMS Content Packaging XML Binding v1.1.4 specification. As such it will be used as the basis for the production of the following v1.1.4 documents:

  • IMS Content Packaging XML XSDs;
  • IMS Content Packaging Best Practice and Implementation Guide [CP, 04c].

This binding has been derived from the agreed IMS Content Packaging Information Model v1.1.4 [CP, 04a] and conforms to the XML 1.0 Specification [XML, 98] of the W3C. Version 1.1.4 is a maintenance release update to the version 1.1.3 specification and a description of the changes is given in the accompanying addendum documents [CP, 04d].

A list of future planned enhancements can be found in Appendix D of the Best Practice Guide [CP, 04c]

2. XML Basics

The Content Packaging data model can be defined as a hierarchy. Hierarchical models are convenient for representing data consisting of many elements and sub-elements. XML is perfectly suited for representing hierarchical models. An XML document is a hierarchy comprised of elements that have contents and attributes.

2.1 Elements

An element is a component of a document that has been identified in a way a computer can understand. Each element has a tag name. When a tag name is shown as "<TAGNAME>", with less-than and greater-than symbols before and after the tag name, it serves as the start-tag to mark the beginning of an element. When that same tag name has a forward slash "/" added, it serves as an end-tag such as "</TAGNAME>". An element may have contents between its start and end-tags, and may have one or more attributes. When an XML element has a start and end-tag (also called an opening and closing tag) with a common name, it is considered to be "well-formed" XML. The contents of an element are placed between the start and end-tags as shown below:

<TAGNAME>contents</TAGNAME>

2.1.1 Element Contents

An element may contain other elements, Parsed Character Data (PCDATA), Character Data (CDATA), or a mixture of PCDATA and elements. The allowable contents of an element are its content model. PCDATA really means any character string that does not contain elements. PCDATA is what the bulk of elements will use between their start and end-tags. CDATA is different in that it is a method for adding any character data that should not be processed. For example, you could add some JavaScript code instructions using a CDATA section. A CDATA section tells the parser not to look for any mark-up until after it locates the end of the CDATA section.

2.1.2 Element Attributes

An attribute provides additional information about an element. Attributes are a way of attaching characteristics or properties to the elements of a document. An element may have more than one attribute. Attributes are contained within the start tag of an element. Attributes are represented by an attribute name followed by an equal sign and the attribute value in quotation marks:

<timeframe> 
   <begin restrict="1"> 1999-07-23 </begin>
</timeframe>

In this example, the <timeframe> element contains another element: the <begin> element. The <begin> element has one attribute 'restrict', with the value "1". The value for the element <begin> is "1999-07-23". These two elements then make up a timeframe begin date.

2.1.3 Element Names

Each element has a unique name, referred to as the tag name. XML is case-sensitive in its processing of tag names. The IMS Content Packaging XML Binding adheres to the following tag name rules:

  • All tag names will conform to the rules for element naming as given within the XML 1.0 Specification.
  • Names beginning in XML in any case or mix of cases are not permitted.
  • The IMS binding will use only lowercase tag and element names.
  • Element names may not include words reserved by the XML specification. These include:
    DOCTYPE
    ELEMENT
    ATTLIST
    ENTITY
  • Tag names defined by the IMS binding may not be redefined.

2.2 Document Type Definitions

The tag name, content model, and attributes of elements are defined in a Document Type Definition (DTD) statement. This may exist as an external file or a block of text internal to an XML document. Internal DTDs are used to override elements defined in external DTD files, so an internal DTD should be used with care. The DTD defines the elements that may be used and may define the contents of the elements.

This specification defines a DTD (imscp_rootv1p1.dtd) as a non-normative reference. Some XML editors may make use of a DTD to help guide the developer in creating the proper elements at the proper locations in an XML file. Other developers will make use of DTDs to validate their XML documents to ensure their document is consistent with all of the element names and locations defined in the DTD. Details of the construction of DTDs are outside the scope of this document, but links to the XML 1.0 Specification are included in section 1.5 of this document.

2.3 XML Schemas

A schema is a formal specification of element names that indicates which elements are allowed in an XML document, and in which combinations. New schema languages, such as those defined in the XML-Schemas Working Group, provide the same baseline functionality as a DTD. However, because these schema languages are extensible, developers can augment them with additional information, such as data types, inheritance, and presentation rules. This makes these new schema languages far more powerful than DTDs. For more information about XML schemas, there is a link to the W3C XML Schema Recommendation in section 1.5.

This specification defines a W3C XML Schema as a non-normative reference. Some XML editors may make use of schemas to help guide the developer in creating the proper elements at the proper locations in an XML file. Other developers will make use of schemas to validate their XML documents and/or to define extensions to the IMS Content Packaging Binding. Details of the construction of schemas are outside the scope of this document.

2.4 Valid Character Sets

A Content Packaging record must use UTF-8 or UTF-16 encoding of the character sets as defined in ISO 10646. See the XML Version 1.0 for more details on the specification of well-formed XML.

2.5 Special Handling Requirements

2.5.1 XML Reserved Characters

Some characters used in XML must be escaped when used outside of their XML-defined usage as found in section 2.4 of the XML 1.0 Specification. These characters are ampersand (&), less than (<), greater than (>), apostrophe ('), and the double-quote character (").

These characters may be represented using either numeric character references or the strings "&", "<", ">", "&apos;", and """.

Below is a more complete quote from the W3C XML standards:

Quote from Extensible Markup Language (XML) 1.0
W3C Recommendation 10-February-1998
2.4 Character Data and Markup

"Text consists of intermingled character data and markup. Markup takes the form of start-tags, end-tags, empty-element tags, entity references, character references, comments, CDATA section delimiters, document type declarations, and processing instructions.

"All text that is not markup constitutes the character data of the document.

"The ampersand character (&) and the left angle bracket (<) may appear in their literal form only when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. They are also legal within the literal entity value of an internal entity declaration; see "4.3.2 Well-Formed Parsed Entities". If they are needed elsewhere, they must be escaped using either numeric character references or the strings "&" and "<" respectively. The right angle bracket (>) may be represented using the string ">", and must, for compatibility, be escaped using ">" or a character reference when it appears in the string "]]>" in content, when that string is not marking the end of a CDATA section.

"In the content of elements, character data is any string of characters, which does not contain the start-delimiter of any markup. In a CDATA section, character data is any string of characters not including the CDATA-section-close delimiter, "]]>".

"To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as "&apos;", and the double-quote character (") as """."

2.5.2 White Space Handling

Questions often arise as to whether Web-based data transmission tools might inadvertently strip off or transform some of the white space characters embedded in data transmitted between systems using XML. To eliminate concern about this issue, refer to the following quote from the W3C XML standards, which indicate that all white space must be preserved where it is part of the data.

Quote from Extensible Markup Language (XML) 1.0
W3C Recommendation 10-February-1998
2.10 White Space Handling

"In editing XML documents, it is often convenient to use "white space" (spaces, tabs, and blank lines, denoted by the non-terminal S in this specification) to set apart the mark-up for greater readability. Such white space is typically not intended for inclusion in the delivered version of the document. On the other hand, "significant" white space that should be preserved in the delivered version is common, for example in poetry and source code.

"An XML processor must always pass all characters in a document that are not mark-up through to the application. A validating XML processor must also inform the application which of these characters constitute white space appearing in element content.

"A special attribute named xml:space may be attached to an element to signal an intention that in that element, white space should be preserved by applications. In valid documents, this attribute, like any other, must be declared if it is used. When declared, it must be given as an enumerated type whose only possible values are "default" and "preserve". For example:

"<!ATTLIST poem xml:space (default|preserve) 'preserve'>

"The value "default" signals that applications' default white-space processing modes are acceptable for this element; the value "preserve" indicates the intent that applications preserve all the white space. This declared intent is considered to apply to all elements within the content of the element where it is specified, unless overridden with another instance of the xml:space attribute."

3. Narrative Description of XML Binding

This specification defines the XML format using narrative. XML DTDs and XML Schemas that implement this abstract format are referenced as non-normative parts of this specification.

3.1 <manifest> Elements

Description. The first, top-level <manifest> element in the Manifest encloses all the reference data. Subsequent occurrences of the <manifest> elements inside the top-level <manifest> are used to compartmentalize files, meta-data, and organization structure for aggregation, disaggregation, and reuse. The best-practice use of the IMS Content Packaging specification will result in each "learning object" or "atomic unit of learning" being placed within its own <manifest> element.

3.5 Extensibility

The IMS Content Packaging XML Binding is extensible through the use of XML Namespaces and XML Schemas. It is expected that the extensibility mechanism will be used to describe additional types of meta-data, organizations, and resources. More information and examples of extensibility are contained in the IMS Content Packaging Best Practice Guide [CP, 04c].

\schema\ imscp_v1p1.xsd IMS Content XML Schema, version 1.1.4
\samples\All_Elements Illustrates a simple manifest using Content Packaging elements.
\samples\QTI_Example Illustrates a simple manifest packaging QTI elements.
\samples\Full_Metadata Illustrates a manifest that uses all elements and attributes defined in the IMS Content Packaging specification.
\samples\Multiple_Organizations Illustrates the use of multiple <organizations>, to provide different paths through a course.
\samples\Simple_Manifest Illustrates a simple manifest.
\samples\Sub_Manifests Illustrates the use of sub-Manifests to promote reuse. This example takes the Simple Manifest example, and implements it using sub-Manifests.

The W3C 'xml:' namespace definition file is available online but in cases where the parser does not have internet access, users may modify the schema to reference a local version of 'xml.xsd' that has been retrieved from W3C and associated with the same namespace. In these cases the local version is a control document and as such it should be in the root directory along with the manifest file itself.

The filename of the Content Packaging control XSD only identifies the primary and secondary versions of the version i.e., for the v1.1.4 release the XSD filename is 'ims_cpv1p1.xsd'. The full version number is recorded in the 'version' attribute on the schema declaration e.g.,:

<xsd:schema targetNamespace="http://www.imsglobal.org/xsd/imscp_v1p1" 
   xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://www.imsglobal.org/xsd/imscp_v1p1" 
   elementFormDefault="qualified" version="IMS CP 1.1.4">

Revision History

Version No. Release Date Comments
Final 1.0 25 May 2000 Updated document to address the following open issues:
a) Explained basic differences between DTDs and other Schemas for document validation in both the Best Practice Guide and the Binding document;
b) Ensured that the samples provided with the specification are separated into different folders depending on whether a DTD or an XDR file is used as the control document. The samples used in the body of the specification documents are only well-formed and do not rely upon a particular control document;
c) Added a URL for where users can download the samples;
d) Made an explicit comment that none of the samples provided (wherever they occur) refer to any sort of control document;
e) Reordered the Appendices to fit the order they're mentioned in the specification documents.
Final 1.1 19 April 2001 Updated document to address the following open issues:
a) Clarified the use of the <organization> element in section 3.3.1;
b) Deprecated the use of XInclude: removed samples from Sections 4.6 and 4.7;
c) Extended meta-data functionality to <organization>, <item>, and <file>;
d) Changed the 'type' attribute on <organization> to 'structure' with a default value of 'hierarchical';
e) Added <dependency> element to Section 3.4.1.3;
f) Added sample of meta-data on <organization> to Section 3.3.4;
g) Deprecated the use of <manifestref> and moved (sub)Manifests out of the <resources> block;
h) Changed resource <item> element attribute back to 'identifierref' from 'resourceref';
i) Made several minor edits; changed references to sub-manifest to (sub)Manifest; updated the graphics;
j) Added <dependency> example to Section 3.4.1.3.
Final 1.1.1 23 May 2001 Updated XML-Schema sample in Binding Appendix B.
Final 1.1.2 08 August 2001 Made several editorial corrections, and:
a) Corrected references from a specific IMS Meta-Data version to just IMS Meta-Data;
b) Removed the copies of the DTD and XSD from the appendix for ease of updating in the future;
c) Removed references to XDR (XML Data Representation) schema, since it is no longer supported by Microsoft.
Final 1.1.3 12 June 2003 The changes contained within v1.1.3 are:
a) 'xml:' prefix recommendation - adoption of the W3C 'xml.xsd' file for the definition of the 'xml:' namespaced attributes available to the content package;
b) XML binding version identification attribute - clarification on the version numbering and corresponding namespace consequences for the content package XML schema;
c) ID and IDREF usage in the XML binding - clarification on the implications of the usage of the 'xsd:ID' and 'xsd:IDREF' features in the content package XML schema;
d) XML binding min/max constraints relaxation - removal of the min/max constraints that are currently incorrectly imposed within the content package XML schema;
e) 'parameter' attribute vocabulary - adoption of a syntax for the definition of the parameters as contained in the 'parameter' attribute plus definition of the algorithm to construct an associated URI;
f) 'isvisible' attribute clarification - clarification on the consequences on the rendering of the content and its title due to the usage of the 'isVisible' attribute;
g) 'type' attribute vocabulary - clarification on the usage of the 'webcontent' and other terms permitted for the 'type' attribute vocabulary
h) 'Href' filename format recommendation - formal definition of the file name formats that must be adopted when using the 'Href' attribute;
i) ZIP file format recommendation - formal definition of the ZIP file format that must be adopted;
j) Submanifest usage best practices clarification - clarification on the permitted referencing between a manifest and its contained (sub)Manifests.
Final 1.1.4 04 October 2004 Made several editorial and clarifying corrections, and:
a) Corrected inconsistent name-spacing using xml:lang and x:lang;
b) Clarified conflicting information describing the <organizations> element;
c ) Removed remaining references to the <variation> element;
d) Coordinated Item element multiplicity between Info Model and Binding documents;
e) Corrected all graphics to be consistent with the v1p1p4 schema.
