Bug ID: 137764
Summary: New Writer formula functions should use dedicated
namespace in ODF
Product: LibreOffice
Version: 7.1.0.0.alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: mikekagan...@hotmail.com
CC: michael.st...@cib.de, nem...@numbertext.org,

In tdf#123388, tdf#123354, tdf#123390, tdf#123356, new functions were added to
formulas in Writer: PRODUCT, ABS, SIGN, COUNT.
They all are written into ODF using usual syntax, e.g. in text:formula
attribute of text:expression element, or in table:formula attribute of
table:table-cell element.
These attributes are defined as "The attribute value should begin with a
namespace prefix followed by ":" (U+003A, COLON), followed by the text of the
formula. The namespace bound to the prefix determines the syntax and semantics
of the formula".
The namespace used in current master for these formulas is
xmlns:ooow="http://openoffice.org/2004/writer";. It looks like we expect any
application that supports the old OpenOffice formulas to support these new
added functions.
Should we introduce a special namespace for the formulas with new functions?
Maybe have the functions standardized in a next version of ODF standard (as a
common standardized set of functions and formula syntax)? Otherwise, we risk
having multiple incompatible extensions/implementations of the formulas for
Writer.
