2 Features:

Features:

downloadable sources and information the community and communication mechanisms for the project The governance body called the Open Office.org Foundation

To create an open and ubiquitous XML-based file format for office documents and to provide an open reference implementation for this format. XML adopted as the new native file format for the Star Office™ suite, replacing the old binary file format.

4 Goal

Goal

Two Fold Complete specification encompassing all Star Office components Provide an open standard for office documents

5 Why XML

Why XML

Ideal open standard because of the free availability of XML specifications DTDs XSL, XSLT, XLink, SVG, MathML One single XML format can be applied to different types of documents

6 XML File Format Specification

XML File Format Specification

Name Spaces Structure Document Info

7 Name Spaces

Name Spaces

Office Style Api Table Meta Draw

8 Structure

Structure

Element symbolizes structural components The structure applies to all applications Text,spreadsheet,drawing… all differ only by content and all are represented by the same structure

9 Document Root

Document Root

Root – ‘document’ XML code <office:document> DTD <!ELEMENT office:document (office:meta?,office:configs?,office:scripting?,…)>

10 Root element Attributes

Root element Attributes

‘Class’ –identifies document application text on-line text Spreadsheet Drawing Presentation XML code: office:class

11 Version Gives the version of the file format XML code: office:version

Version Gives the version of the file format XML code: office:version

DTD : <!ATTLIST office:document office:version CDATA #implied>

12 Document Information

Document Information

Title Author Document creation date Specified using ‘meta’ element XML code <office:meta>

13 Others

Others

Scripting Forms Styles Configuration management

14 Document Content

Document Content

‘body’ element contains content XML code :<office:body> DTD <!ELEMENT office:body ANY> ‘ANY’ indicates any type of content

15 White Space processing & EOL handling

White Space processing & EOL handling

White spaces ignored for elements that have element contents Preserved by default Line feed & carriage return for line ends Entity reference &#x0D

16 Document Validation

Document Validation

If document is validated it must match the DTD Not appropriate to validate in following cases 1. Documents created by another version 2. Documents that contain a custom extension

17 Why not Validate

Why not Validate

Both documents may contain elements & attributes that may be unknown to the application processing the file Forward compatible processing rules describes how to handle such elements

18 RULES

RULES

Major version same as current major version & minor version same or less than current minor version then FCP is “DISABLED” The document may be validated

19 RULES

RULES

If major version same as current major version and minor version greater than current minor version FCP “ENABLED” Document should not be validated The same thing holds good when major versions are not equal

20 Preserving unknown attributes

Preserving unknown attributes

Attributes preserved by default Some attributes corrupt document.These should not be preserved <?staroffice:preserve excl-attrs = “….”?> …. Is any valid xpath expression

21 Language element

Language element

Language element specifies default document language XML Code <dc:language> DTD <!ELEMENT dc:language ‘language code’>

22 DATA STYLES

DATA STYLES

Displaying different types of data Number style <number:number-style> Currency <number:currency-style> Date <number:time-style> Boolean Text …

23 HANDLING HYPERLINKS

HANDLING HYPERLINKS

Hyperlinks in text documents are represented by a simple XLink XML Code: <text:a> Rules: If this element contains white-space characters, the characters are collapsed DTD: <!ELEMENT text:a (script:events?,(%inline-text;)*)>

24 ATTRIBUTES

ATTRIBUTES

The attributes associated with the <text:a> element are: Name Link locator Target frame Text styles

25 NAME

NAME

A hyperlink can have a name, but it is not essential. The name attribute specifies the name of the hyperlink if one exists. This name can serve as a target for some other hyperlinks.

26 XML –CODE text:name DTD: <

XML –CODE text:name DTD: <

ATTLIST text:a text:name CDATA #IMPLIED> Notes: This attribute is specified for compatibility with HTML where an <a> element may serve as link source and target simultaneously

27 Target Frame

Target Frame

The target frame name of the link is specified by a ‘target- frame- name’ attribute XML Code: office:target-frame-name

28 RULES

RULES

" _self “referenced document replaces current frame " _blank “ referenced document displayed in a new frame " _parent “referenced document displayed in the parent frame of the current frame

29 RULES

RULES

" _top” The referenced document is displayed in the uppermost frame A frame name referenced document is displayed in the named frame

30 XLINK SPECIFICATION

45 CHARTS

CHARTS

Can exist as standalone docments or as documents inside XML documents To create a standalone chart document set the value of the ‘office:class’ attribute to chart in the <office:document> element Chart data is contained in <table:table> element

46 CHART INSIDE SPREADSHEET

CHART INSIDE SPREADSHEET

To reference the correct table and cells you can use the table:cell-range-address attributes, which are applied to the <chart:series> elements that represent the data series in the chart
