Draft:Signal Metadata Format
| Submission declined on 18 November 2023 by Ca (talk). I recommend a merge to GNU Radio. Except for the "Proceedings of the GNU Radio Conference", the other listed sources doesn't have much to say about it.
For example, this and this only mentions that the dataset uses the time format, and give no info about it.

Comment: The most recent reason for declining is that the second section is "unsourced". I'm honestly not sure how to source t hose comments. I say that HDF5 and flat files were used prior to SigMF. If you search on IEEE Xplore (journal search), you can see that there are several papers from 1999 to 2019 using this kind of container. A similar search for SigMF yeilds only two papers, but they are from 2021-2023. Unfortunately the dataset format isn't often discussed in the paper itself. I say that VITA49 is a transport standard, and the full title of VITA49 is "VITA Radio Transport Standard". I have also posted a request for help on wikiproject radio, but IMO this page is pretty clean at the moment. Teque5 (talk)
- Comment: Restructured page, added section on history. With respect to most recent comment from WikiOriginal-9, I have provided citations from journals, industry, and US government sources so I can only surmise the page was skimmed too quickly. Please compare this proposed page on the SigMF standard to ASDF, which refers to a similar scientific topic. I believe this page is ready. Teque5 (talk) 17:36, 15 November 2023 (UTC)
- Comment: Not enough independent, significant coverage. WikiOriginal-9 (talk) 13:26, 7 November 2023 (UTC)
- Comment: Added another citation for VITA 49 (second section as mentioned) since the wikipedia page doesn't exist yet. Two months ago I opened a discussion on wikiproject radio (also suggested below) and had no contributions. I think this article is very ready. Please compare it to the ASDF standard used for astronomical images that came about more recently than SigMF. Teque5 (talk) 09:05, 10 October 2023 (UTC)
- Comment: Added note showing adoption by National Instruments and additional citation. Teque5 (talk) 17:33, 29 August 2023 (UTC)
- Comment: As suggested before, please post a note at WikiProject Radio. I did check JSTOR and Proquest but did not get anything, however, I am happy to defer to their expertise. S0091 (talk) 19:44, 15 October 2022 (UTC)
- Comment: @Stuartyeates There are now (2) Academic sources, (1) US Government reference, and (1) commercial reference in this article. Please compare this page to Advanced_Scientific_Data_Format for a related industry standard. Teque5 (talk) 19:29, 15 October 2022 (UTC)
- Comment: @S0091 The GNU Radio proceedings have 7 years of publications. I'm surprised Wikipedia is so picky. Perhaps I can find some additional IEEE references Teque5 (talk) 19:29, 15 October 2022 (UTC)
- Comment: The first source is not a reliable source so should not be used. It may be a good idea to seek guidance at WikiProject Radio. S0091 (talk) 16:26, 14 October 2022 (UTC)
- Comment: There are none of them seem to be the kind of independent secondary sources that we're looking for. Stuartyeates (talk) 21:48, 15 July 2022 (UTC)

Signal Metadata Format (SigMF) is a standardized representation for recorded digital signal time series, typically encompassing real or complex-valued radio signals, acoustic waves, antenna positions, or sensor voltages.[1] The metadata is encapsulated in a JSON file with a .sigmf-meta extension, usually situated alongside the binary data stored in a file with a .sigmf-data extension. Extensions enable the addition of hierarchical data to a complete dataset, a capture, or a specific region of the recording.
History[edit]
Before the standardization of SigMF, time series data representing radio signals were commonly stored in flat binary files with external descriptors. Occasionally, researchers used Hierarchical Data Format (HDF5) containers (.hdf5), but these containers lack specificity to any data type. The VITA Radio Transport Standard a.k.a. VITA 49 (.vrt) was at times employed for RF data storage, although it is primarily designed as a transport format for RF signals rather than for data storage purposes[2]. Other proprietary formats were created by industry either to hold specific metadata or encode signals into proprietary containers.
In 2016 at the annual GNU Radio conference, a workshop focused on how a better open source container for RF signals could be constructed and maintained. In the following year the initial release of SigMF was created to provide a portable & annotated container for radio signals.
