Official texts of OECD Legal Instruments in both OECD official languages (English and French), as well as related information, are made available in the Compendium of OECD Legal Instruments at https://legalinstruments.oecd.org. OECD Legal Instruments may be found elsewhere, including on OECD websites, but You should always consult the Compendium, as it is the only source of the official and up do date texts and information.
You may reproduce and distribute individual OECD Legal Instruments free of charge and without requesting any permissions, as long as You do not alter them in any way. You may use excerpts of a Legal Instrument, as long as You ensure that the legal nature/integrity of the Instrument is preserved and the excerpt is not used out of context or provides incomplete information or otherwise mislead the reader as to the actual legal nature, scope or content of the Legal Instrument. OECD Legal Instruments may not be sold but may be used in the context of commercial activities such as, for example, consulting or training services.
OECD Legal Instruments are available in the two OECD official languages (English and French). Translations into other languages may be available on the website, but the only official texts remain the English and French versions.
You may translate OECD Legal Instruments and related information and documents provided in the Compendium into other languages, as long as the translation is labelled “unofficial translation” and You include the following disclaimer: “This translation has been prepared by [translation author] for informational purpose only and its accuracy cannot be guaranteed by the OECD. The only official versions are the English and French texts available on the OECD website https://legalinstruments.oecd.org.
We encourage You to provide your translation (PDF format) to the OECD, e-mail firstname.lastname@example.org
The OECD makes data (the “Data”) available for use and consultation by the public. Data may be subject to restrictions beyond the scope of these Terms and Conditions, either because specific terms apply to those Data or because third parties may have ownership interests. It is the User’s responsibility to verify, either directly in the metadata or, if available, by clicking on the icon and then referring to the "source" tab, whether the Data is fully or partially owned by third parties and/or whether additional restrictions may apply, and to contact the owner of the Data before incorporating it in your work in order to secure the necessary permissions. The OECD in no way represents or warrants that it owns or controls all rights in all Data, and the OECD will not be liable to any User for any claims brought against the User by third parties in connection with the use of any Data.
Except where additional restrictions apply as stated above, You can extract from, download, copy, adapt, print, distribute, share and embed Data for any purpose, even for commercial use. You must give appropriate credit to the OECD by using the citation associated with the relevant Data, or, if no specific citation is available, You must cite the source information using the following format: OECD (year), (dataset name),(data source) DOI or URL (accessed on (date)). When sharing or licensing work created using the Data, You agree to include the same acknowledgment requirement in any sub-licenses that You grant, along with the requirement that any further sub-licensees do the same.
Availability of Data
The availability of the Data is contingent upon the availability of the OECD’s corresponding resources, whose capacity is subject to change at any time. The OECD may monitor your use of the Data and reserves the right, at its sole discretion and without limitation, to modify the amount of Data You may request in a single query, to modify the number of queries You may make over a specified time, to remove certain Data and to alter the file formats in which Data are available.
OECD Application Programming Interfaces (APIs)
You may use one or more OECD-developed application programming interfaces (“APIs”) to facilitate access to the Data. APIs are made available on an “as-is” basis, and use of an API is at your own risk. In particular, but without limitation, the OECD disclaims all warranties as to an API’s compatibility with your hardware and software and accepts no liability for any damages or claims arising out of or in connection with your use of an API and/or the underlying Data accessed through an API. For the avoidance of doubt, the OECD accepts no obligation to provide technical, administrative or other support in connection with the APIs or for any other purpose. The OECD may decide to suspend or terminate the provision of the APIs and API-accessible Data at any time.
The OECD may release updated versions of the APIs from time to time and at its sole discretion. Once the OECD releases updated versions, previous APIs may no longer function properly, and You therefore agree, for each API, to use the most up-to-date version available.
You agree not to modify, distribute, decompile, disassemble, reverse engineer or perform any similar action on the APIs or any of their portions or components.
The OECD reserves the right to limit or suspend any User’s IP address access to the APIs at any time and without notice for any reason, including if the OECD determines that You are using or are attempting to use the Data and/or the APIs in violation of these Terms and Conditions in such a way as to harm the OECD or any other party, or if You are placing too great a strain on the infrastructure necessary for making the Data available to a reasonable number of people. You agree not to use any technical means to interfere with the OECD’s monitoring of usage of the above-mentioned resources. The OECD reserves the right to use any technical means to overcome attempted technical interference with usage monitoring. Finally, the Data and the APIs will be unavailable from time to time, at the OECD’s sole discretion, for periodic maintenance.
As noted above, these Terms and Conditions may be updated from time to time. By using an API, You agree to periodically review these Terms and Conditions, to take note of any changes thereto, and to adapt your usage of the API accordingly.
You shall not do any of the following in any messaging or communication facilities that may be found on an OECD Website:
The OECD reserves the right to deny, at its sole discretion, any User’s IP address online access to the OECD Websites or any portion thereof without notice.
You specifically acknowledge and agree that the OECD is not liable for any conduct of any other User, including, but not limited to, the types of conduct listed above.
In order to promote its work, and because linking is an essential aspect of the Internet, the OECD encourages You to include hyperlinks to the OECD Websites without having to ask prior permission, under the following conditions:

Send your request to firstname.lastname@example.org. If permission is granted, it is only granted for the specific usage referred to in OECD’s reply; each new use requires a new request.

The Republic of Cyprus is recognised by all members of the United Nations with the exception of Türkiye. The information in the documents relates to the area under the effective control of the Government of the Republic of Cyprus.
