About the OTP format
ODP is the OpenDocument presentation — LibreOffice Impress’s native format, built on the same zip-of-XML idea as PPTX. Files come from public institutions, lecture archives and anyone standardised on open formats.
As with PPTX, text extraction gives you every word in slide order, without the visuals. That is usually exactly what lecture notes and published deck archives are for.
