Text and Data Mining Reservation Protocol Community Group

The goal of this Group is to facilitate Text and Data Mining (TDM) Reservation Protocol in Europe and elsewhere, by specifying a simple and practical machine-readable solution, capable of expressing the reservation of TDM rights - following the rules set by the new European DSM Directive / Art.4 - and the availability of machine-readable licenses for TDM actors.

Kickoff of the TDM Reservation Protocol CG

Dear participants in the Text and Data Mining Reservation Protocol CG (TDMrep in short), it has taken some time for the co-chairs before inviting you to a first call; this is simply because we were waiting a sufficient number of participants representing TDM actors. We are currently 13 participants in this CG, and we are expecting other people to join now that we have reached ACReps from organizations which have a foot in TDM.

Therefore it is now time to have a kickoff call, and Giulia and I propose to have it between Feb. 15th and 23th.

For that purpose we have setup this Doodle. Please fill it to signal your availability.

We will use Zoom for the call, please contact the co-chairs to get details (it is bad practice to let that in a blog post).

Before the call, you can read the documents which have been put in place in the project Github space. The most important is certainly the set of requirements which should be discussed and – if possible – validated during the first call. A proposed charter for the CG is also to be discussed and validated asap.

The repository also includes a proposal for a common vocabulary, a tentative to define TDM and some useful extracts of the EU DSM Directive (Articles 3 and 4). All good reads.

Giulia and I hope to meet you all at this kickoff call 🙂

Context of the TDM Reservation Protocol initiative

In addition to their significance in the context of scientific research, text and data mining techniques (TDM) are widely used both by private and public entities to analyse large amounts of data (including copyright protected content like text, images, video etc.) in different areas of life and for various purposes, including for government services, complex business decisions and the development of new applications or technologies.

In a digital environment, TDM usage of copyright protected works can be subject to different terms and conditions, depending on the legal framework. In generic terms, an act of reproduction is required before TDM can be applied on content accessible on the Web; international laws stipulate that such act of reproduction is subject to authorization by rightsholders. So far, analyzing and processing the terms and conditions of a website, contacting rightsholders, seeking for permission and concluding licensing agreements require time and resources.  

In such context, a machine-readable solution which streamlines the communication of TDM rights and licenses available for online copyrighted content is necessary to facilitate the development of TDM applications and reduce the risks of legal uncertainty for TDM actors. Such a solution, that shall rely on a consensus by rightsholders and TDM actors, will optimize the capacity of TDM actors to lawfully access and process useful content at large scale.

The EU Directive 2019/790, better known as the DSM Directive (DSM meaning Digital Single Market), introduces two exceptions or limitations to the rights of rightsholders on lawfully accessible content, for reproductions and extractions for the purposes of TDM:

  • In its Article 3, a mandatory exception for research organisations and cultural heritage institutions which carry out TDM for the purposes of scientific research.
  • In its Article 4, an exception for any organisation willing to carry out TDM  for any purpose other than scientific research, including commercial purposes, which applies on the condition that the use of content for TDM has not been expressly reserved by their rights holders in an appropriate manner, such as machine-readable means. 

These TDM exceptions apply to TDM usage in the European Union in relation to content from European and foreign rightsholders. Outside of the EU, where the DSM legislation does not apply, the said exception does not apply: exclusive rights of right-holders to authorize acts of reproduction are maintained. In such cases, no TDM can be performed without the explicit authorisation of these rightsholders: in these countries, the absence of a reservation of rights by rightsholders cannot be considered as an implicit authorization to reproduce copyrighted content for TDM purpose, and advocating fair use or a similar rule is legally uncertain, as these actions are judged on a case-per-case basis.

The “opt-out” mechanism introduced by the DMS Directive is therefore a real opportunity for TDM actors and publishers across countries to define a machine-readable technique able to express not only if TDM rights on specific Web content are reserved or not, but also how rightsholders can be contacted and which licenses are available, if any. This is a tremendous help for TDM actors from all countries looking for legal certainty.

Call for Participation in TDM Reservation Protocol Community Group

The TDM Reservation Protocol Community Group has been launched:


The goal of this Group is to facilitate TDM in Europe and elsewhere, by specifying a simple and practical machine-readable solution, capable of expressing the reservation of TDM rights – following the rules set by the new European DSM Directive / Art.4 – and the availability of machine-readable licenses for TDM actors.


In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2021-01-18 by Laurent Le Meur. The following people supported its creation: Laurent Le Meur, Ivan Herman, ANNE BERGMAN-TAHON, Giulia Marangoni, Catherine Blache. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at site-comments@w3.org

Thank you,
W3C Community Development Team
