On 8 Oct 2015 I listed the LO-5.0.0 Math import/export filters. Those filters are made use of every time we import from, or export to, a LO-Math file. So, 5 years later, what are the current Math filters?

◦ LO-6.x Base filters

◦ LO-6.x Calc filters

◦ LO-6.x Draw filters

◦ LO-6.x Graphics filters

◦ LO-6.x Impress filters

◦ LO-6.x Writer filters

LO-6.4 file-conversion filters

(many thanks to Mike Kaganski for the last link; he says that the filters began to be documented at v6.3)

```
~$ lsb_release -a Devuan GNU/Linux 3 (beowulf)
~$ soffice.bin --version LibreOffice 6.1.5.2 10(Build:2)
```

Hand-extracted from /usr/lib/libreoffice/share/registry/math.xcd

Almost identical to the 5 x LO-5 Math filters:

```
• Filter v6.1.5.2
• media
• file extension(s)
☑ == New entry
☒ == Removed
1 MathML XML (Math)
• application/mathml+xml
• mml
2 math_MathType_3x
• -
• xxx
3 StarOffice XML (Math) (math6)
• application/vnd.sun.xml.math
• sxm
4 math_pdf_Export
• application/pdf
• pdf
5 math8
• application/vnd.oasis.opendocument.formula
• odf
```

*‘MathML XML (Math)’* now has *“UI Name == MathML 2.0”* + it can now be exported as well as imported. That’s the only difference from LO-5 that I can spot.

If this helps then please tick the answer ()
