About TGiT

Digitized music must contain metadata in order to be licensed, searched, tracked and paid for online usage. Whether factual, cultural (tags and folksonomy), contractual-time-sensitive, content based or usage generated, new norms and standards are being defined to acknowledge the increasing role of music metadata.

The TGIT software project is an indexation platform containing music metadata for the use of creators, performers, producers of sound recordings, record labels.

Download of bilingual version (EN/FR) is available for MAC and Windows.

Thanks to some evolution of metadata information, which is progressively being recognized and used by players in the music industry worldwide, TGIT will allow music to register harmoniously and productively in the new global digital ecosystem. TGIT is not a legal online music service nor an audio file agregator. It is strictly limited to the indexing of digital audio recordings and works metadata within the existing framework. During the first phase, Iconoclaste inc. will develop the basic software (an open source “Music Tagger”) for individual (desktop) use. This will allow the initial creators and producers of the copyrighted content to embed the metadata of their works in song files. The software is free for industry professionals. A second phase will involve building a metadata repository in collaboration with the rightsholders sector.

The research on which the TGIT project is based has been published in early 2013. It was carried out by Jean-Robert Bisaillon as part of his master’s degree in Research Practices and Public Action at the Urbanisation Culture Société Research Centre, which is part of the National Institute for Scientific Research (INRS) in Montreal. It sets out the results of a survey conducted on metadata in the field of sound recording, conducted with the support of the Institute’s laboratory / art and society / land and theory department (l / as / tt). This first research project is complemented by a second which focuses more specifically on the knowledge mobilization used in carrying out this research, and the construction and transmission of the results. Beyond this formal academic framework, the project involves a phase of mobilization and implementation which has as its aim the development of the TGIT technical and software capability. The overall aim of the project is to meet the practical needs of industry partners, and, as a logical consequence of research-action, these partners will participate to the new phases of the project.

For the purposes of our study, we have created a list of musical databases which are already in use. At the time of publication, the list contains 60 databases. It is available online under Creative Commons BY-NC-SA, and will be updated repeatedly as the work progresses.  http://bit.ly/musicalmetadata

For the purposes of our study, we have also created a cross-referenced table of metadata fields in order to compare the constants and methodological differences of certain stakeholders. At present, this table brings together and compares more than 280 fields of databases and metadata ID3V2, IODA, CDDB2. SoundExchange, SOPROQ, MusicBrainz, and CISAC CWR V1. The table is available on line, and will be updated repeatedly as we go along. http://bit.ly/metadataframes.

Embedded Metadata Manifesto

The Embedded Metadata Manifesto is an initiative that comes from the world of news agencies and was first conceived as a way to track press photography on the networks. Three agencies have come together to promote it: the IPTC (International Press Telecommunications Council), the 4A (American Association of Advertising Agencies) and the ANA (Association of National Advertisers). TGiT recognizes the value of the Embedded Metadata Manifesto and the transferable nature of its principles for the music and audio-visual industry. Go to the Embedded Metadata Manifesto website

  2. Pythonhttp://www.python.org;
  3. PyQthttp://pyqt.sourceforge.net;
  4. Mutagenhttp://code.google.com/p/mutagen/

The GPL licence forces the programs that use the GPL components to be GPL themselves, and to give free access to the source code on demand. Here’s a summary of the most important points of this licence (of a viral nature). For a complete description of the licences, see: http://opensource.org/licenses. We’ve underlined the points that matter most to our project:

  • Copies may be distributed free of charge or for money, but the source code has to be shipped or provided free of charge (or at cost price) on demand. The receiver of the source code has the same rights meaning he can share copies free of charge or resell.
  • The licensed material may be analysed or modified.
  • Modified material may be distributed under the same licensing terms but don’t have to be distributed.

TGiT is available under the same licensing terms.

Pivot Table of Metadata Frames

For our study, we’ve put together a Pivot Table of Metadata Frames to see the methodological constants and variables in various studied subjects. This table currently compares more than 280 databases (ID3V2, Dublin Core, DDEX, IODA, CDDB2, SoundExchange, SOPROQ, MusicBrainz et CISAC CWR V2.11). This table is available online under the reative Commons BY-NC-SA licence. It will be updated periodically. See the Metadata Frames Table

Typological Table of Musical Metadata

For our study, we’ve put together a Typological Table of Musical Metadata. This table currently contains 60 databases. This table is available online under the Creative Commons BY-NC-SA licence. It will be updated periodically. See the Musical Metadata Table

Bearing Point France and Berklee Fair Music studies struggling to define music metadata standards

This month of July 2015 has witnessed the publication of two important music industry studies on fair remuneration for the music industry stakeholders. The first is European, drafted by Bearing Point, commissioned by the French Ministry of Culture, and the second is American by the Berklee School of Music and partly commissioned by the Kobalt Music Group. Both studies are giving a shot at defining what should be standard metadata fields for the industry. But
