I did some tests on the ODF 1.3 HTML specification and would like to share my notes:
I was happy, to find out that the 102 Object directories within the ODT ZIP are no OLE Objects, but MathML objects and are represented in the XHTML version as well as MathML und are well rendered.Â
At least, I picked one of the 102 the first "/Object 1" and quickly tested it. You may find it close to the search-string "B-Splines. If the" within the document.Â
I did not check all 102 as I am certain, if there are MathML problems such as rendering, everyone could switch to ODT as a representational document. This is nothing to waste time on.
In ODF 1.2 I used several images aside from the specification. Today there are no longer images aside of the HTML specification, I made a quick test on the existence of a former image.Â
In general, if you search for "data:image", you may found 18 occurances of images: 1 JPEG, 11 GIF and 6 png, similar to
<img style="height:4.8819cm;width:4.8819cm;" alt="" src="">
This looks good as well. Again I have only checked one occurrence for all, but 18 is a number quite similar to the number of the previous pictures.
There are two dead links:
Last, but not least. This is something, which I find quite annoying and I hope you will fix for the next release. The naming convention of the RNG grammar files was overtaken from ODF 1.0 and not from ODD 1.2, where new grammar files had been added. As I am generating software directly from the files, I would like to handle the file access by automation and only replace the version string.
