@Tom I'm not sure what you are asking, but this might be relevant:
In this 2010-12-09 document, <http://technet.microsoft.com/en-us/library/cc179199(office.14).aspx#BKMK_Changed> It says that the "The RTF file format is no longer enhanced to include new features and functionality. Features and functionality that are new to Word 2010 and future versions of Word are lost when they are saved in RTF. In addition, Word 2010 supports a new converter interface based on Open XML Formats." I suppose LibreOffice and OpenOffice could make the same statement concerning features and functionality of ODF (now or in the future) that do not map to RTF. In other, more recent statements, there is assurance that RTF 1.9.1 is stable enough for meaningful reference from International Standards even though there is no International Standard for it. There is no indication that Saving documents as RTF and opening documents in RTF format is going away any time soon. As to the quality of RTF support in various software products, this tells us nothing. Those who maintain implementations need to be consulted about problems in their handling of the format. Bugs in the format specification are a different matter. There are Microsoft forums for some discussions on both of those concerns: <http://social.msdn.microsoft.com/Search/en-US/openspecifications?query=RTF&beta=0&ac=8> is a general search. Using "Refine search, By Source:" on the left sidebar is interesting. - Dennis MORE ANALYSIS There are two different statements in the 2010-12-09 quoite, and I don't quite know why the "supports a new converter interface based on Open XML Formats" is mentioned. However, there are ways for OOXML features and functions to be passed to RTF, as I mentioned. I imagine there are or will be features and functions in OOXML (and ODF) that can't be embedded in RTF in any useful way. Also, there is a difference between enhancing the RTF format and using the RTF formats for carrying extended material that is not in RTF format. It would obviously be better to go to an XML-based format, such as OOXML/ODF as a vehicle for interchange in the future. It seems to me that handling the OOXML features that are passed around in RTF requires the ability to faithfully accept OOXML as well [;<). There is a 2011-03-17 statement to ISO considering RTF that assures stability and availability. The 2011-03-17 statement describes the acceptability of referencing RTF specification in International Standards even though there is no International Standard for RTF. (The same considerations apply to the use of Zip in the ODF and OOXML specifications.) RTF is referenced in the IS 29500 specification as a format that OOXML documents can link to, although IS 29500 does not include the RTF specification: "The RTF Specification [for RTF] was last updated in 2008, and the RS Originator [Microsoft] anticipates no further updates. However, the RTF Specification will remain under maintenance and Defect Reports [an ISO technical term] will be fully considered and discussed with SC34 [the OOXML ISO maintenance body]. ... "The RS Originator is willing to consider editorial and non-substantive modifications of the RTF Specification during an associated IS 29500 [OOXML] balloting period, but would not make change which alter normative functions in this RTF Specification." Other text indicates that the RTF specification is freely available and covered under Microsoft's Open Specification Promise, as I have already described. -----Original Message----- From: Tom Davies [mailto:tomdavie...@yahoo.co.uk] Sent: Friday, April 27, 2012 11:36 To: users@global.libreoffice.org Subject: RE: [libreoffice-users] Re: rtf import broken in 3.5.1?

I have no idea what format Tom Davies has in mind. As far as I know it is not RTF. It appears that the RTF specification is quite stable. The format has a built-in provisions for future extensions to specify how a implementations that do not recognize the extension should "fall back" to an understood alternative. Although anyone could use that provision, it seems to me that some future extension will include carrying new features introduced in OOXML (ISO/IEC IS 29500) in RTF via XML-format inserts. That provision is already defined for RTF. The latest versions of the specification are quite comprehensive and are freely available. There is even sample code for processing the RTF data stream. To the best of my knowledge, RTF was not subject to any particular regulatory or legal problems. - Dennis MORE BACKGROUND AND RESOURCES In the work undertaken to satisfy regulatory requirements in the EU and the United States, there was a concerted effort to provide and maintain documentation on interfaces and formats that would provide for interoperability with Microsoft systems. That effort spanned several years. The technical-oversight body that was established to review that work has reported that the specifications are acceptable and that updating for current systems is happening in an acceptable way. RTF is not listed as one of those specifications. The RTF specifications are made available separately from these sets: <http://msdn.microsoft.com/en-us/library/gg134032.aspx>. <http://msdn.microsoft.com/en-us/library/gg134034.aspx> Nevertheless, RTF is covered under the Microsoft Open Specification Promise. See the end of the list at <http://www.microsoft.com/openspecifications/en/us/programs/osp/office-file-formats/default.aspx>. The Open Specification Promise itself and the span of its coverage can be found at <http://www.microsoft.com/openspecifications/en/us/programs/osp/default.aspx>. (Those OpenDocument Format specification versions that Microsoft has participated in, such as ODF 1.2, are also covered.) Finally, Microsoft provides implementation notes that account for deviations and implementation-defined provisions in Microsoft's implementation of public standards. Note the documents [MS-OI29500], [MS-OODF], and [MS-OODF2], among others, in this list: <http://msdn.microsoft.com/en-us/library/gg134034.aspx>. -----Original Message----- From: Milos Sramek [mailto:sramek.mi...@gmail.com] Sent: Friday, April 27, 2012 00:13 To: users@global.libreoffice.org Subject: Re: [libreoffice-users] Re: rtf import broken in 3.5.1?

Dear Tom, do you have any references to those court cases? Sounds very interesting. RTF is in Slovakia one of the officialy approved standards to be used by public administration (besides pdf, odf and HTML). Of course, since MS is everywhere and everybody uses RTF. Information about those court trials would be a nice argument against RTF, the compatibility of which in LO/OO/OOO is really pain. This would show why is it so.
