ODF 1.4 has removed the attribute table:cell-range-address from the chart:plot-area element. So we may write it only in versions < 1.4. The attribute was used to distinguish whether a chart has internal data. The same information is given by the href attribute of the chart:chart element. The actual used cell-range-address values are already given in the chart:axis and chart:series child elements and evaluated from there. A global setting is not needed. The attributes chart:data-source-has-labels, chart:column-mapping and chart:row-mapping are related to the table:cell-range-address attribute. These three attributes are deprecated already in ODF 1.2. Thus we will not write them in ODF 1.4. Their information is given in the chart:axis and chart:series child elements. The order of series is given by the order of the chart:series child elements.

ODF Import and Export Filter Logic
The main library "xo" contains the basic ODF import/export filter
implementation for most applications. The document is accessed
via its UNO API, which has the advantage that the same import/export
code can be used for text in all applications (from/to Writer/EditEngine).
The filter consumes/produces via SAX UNO API interface (implemented in
"sax"). Various bits of the ODF filters are also implemented in
applications, for example [git:sw/source/filter/xml]
.
There is a central list of all element or attribute names in
[git:include/xmloff/xmltoken.hxx]
. The main class of the import filter
is SvXMLImport, and of the export filter SvXMLExport.
The Import filter maintains a stack of contexts for each element being read. There are many classes specific to particular elements, derived from SvXMLImportContext.
Note that for export several different versions of ODF are supported, with the default being the latest ODF version with "extensions", which means it may contain elements and attributes that are only in drafts of the specification or are not yet submitted for specification. Documents produced in the other (non-extended) ODF modes are supposed to be strictly conforming to the respective specification, i.e., only markup defined by the ODF specification is allowed.
There is another library "xof" built from the source/transform directory, which is the filter for the OpenOffice.org XML format. This legacy format is a predecessor of ODF and was the default in OpenOffice.org 1.x versions, which did not support ODF. This filter works as a SAX transformation from/to ODF, i.e., when importing a document the transform library reads the SAX events from the file and generates SAX events that are then consumed by the ODF import filter.
OpenOffice.org XML File Format
There is some stuff in the "dtd" directory which is most likely related to the OpenOffice.org XML format but is possibly outdated and obsolete.
Add New XML Tokens
When adding a new XML token, you need to add its entry in the following three files:
[git:include/xmloff/xmltoken.hxx]
[git:xmloff/source/core/xmltoken.cxx]
[git:xmloff/source/token/tokens.txt]
