Apologies, I meant to send this as plain text.
There is provision for extensions that handle such things.
It is through the csymbol element. For example, a
sparse matrix representation could be defined so that
For example, you could write:
<apply><csymbol definitionURL=".../SparseMatrix">SparseMatrix</csymbol>
<vector><cn>5</cn><cn>5</cn><cn>
<vector><cn>1</cn><cn>1</cn><cn> 3.232432423</cn></vector>
<vector><cn>1</cn><cn>2</cn><cn> 3.01</cn></vector>
<vector><cn>1</cn><cn>5</cn><cn> 3.43543453</cn></vector>
</apply>
to mean a 5 by 5 sparse matrix with the a[i,j] specified for selected
coordinates. Column defined matrices could be handled in a similar
manner.
The presentation is handled via XSLT and can range from something
as simple as listing the non-zero table entries, c/w coordinates, through
to generating an actual matrix.
What is needed is an agreed apon vocabulary and then
references to those definitions. Building such a vocabulary
is one of the goals of the OpenMath project. The MathML content
definitions match (or will shortly) a specific collection of those
definitions. Both groups are tracking changes closely.
