Any use of the Work,+other than as authorised under this Licence is prohibited (to the extent such+use is covered by a right of the copyright holder of the Work).++The Work is provided under the terms of this Licence when the Licensor (as+defined below) has placed the following notice immediately following the+copyright notice for the Work:++        Licensed under the EUPL++or has expressed by any other means his willingness to license under the EUPL.++1. Definitions++In this Licence, the following terms have the following meaning:++- ‘The Licence’: this Licence.++- ‘The Original Work’: the work or software distributed or communicated by the+  Licensor under this Licence, available as Source Code and also as Executable+  Code as the case may be.++- ‘Derivative Works’: the works or software that could be created by the+  Licensee, based upon the Original Work or modifications thereof. This Licence+  does not define the extent of modification or dependence on the Original Work+  required in order to classify a work as a Derivative Work; this extent is+  determined by copyright law applicable in the country mentioned in Article 15.++- ‘The Work’: the Original Work or its Derivative Works.++- ‘The Source Code’: the human-readable form of the Work which is the most+  convenient for people to study and modify.++- ‘The Executable Code’: any code which has generally been compiled and which is+  meant to be interpreted by a computer as a program.++- ‘The Licensor’: the natural or legal person that distributes or communicates+  the Work under the Licence.++- ‘Contributor(s)’: any natural or legal person who modifies the Work under the+  Licence, or otherwise contributes to the creation of a Derivative Work.++- ‘The Licensee’ or ‘You’: any natural or legal person who makes any usage of+  the Work under the terms of the Licence.++- ‘Distribution’ or ‘Communication’: any act of selling, giving, lending,+  renting, distributing, communicating, transmitting, or otherwise making+  available, online or offline, copies of the Work or providing access to its+  essential functionalities at the disposal of any other natural or legal+  person.++2. Scope of the rights granted by the Licence++The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,+sublicensable licence to do the following, for the duration of copyright vested+in the Original Work:++- use the Work in any circumstance and for all usage,+- reproduce the Work,+- modify the Work, and make Derivative Works based upon the Work,+- communicate to the public, including the right to make available or display+  the Work or copies thereof to the public and perform publicly, as the case may+  be, the Work,+- distribute the Work or copies thereof,+- lend and rent the Work or copies thereof,+- sublicense rights in the Work or copies thereof.++Those rights can be exercised on any media, supports and formats, whether now+known or later invented, as far as the applicable law permits so.++In the countries where moral rights apply, the Licensor waives his right to+exercise his moral right to the extent allowed by law in order to make effective+the licence of the economic rights here above listed.++The Licensor grants to the Licensee royalty-free, non-exclusive usage rights to+any patents held by the Licensor, to the extent necessary to make use of the+rights granted on the Work under this Licence.++3. Communication of the Source Code++The Licensor may provide the Work either in its Source Code form, or as+Executable Code. If the Work is provided as Executable Code, the Licensor+provides in addition a machine-readable copy of the Source Code of the Work+along with each copy of the Work that the Licensor distributes or indicates, in+a notice following the copyright notice attached to the Work, a repository where+the Source Code is easily and freely accessible for as long as the Licensor+continues to distribute or communicate the Work.++4. Limitations on copyright++Nothing in this Licence is intended to deprive the Licensee of the benefits from+any exception or limitation to the exclusive rights of the rights owners in the+Work, of the exhaustion of those rights or of other applicable limitations+thereto.++5. Obligations of the Licensee++The grant of the rights mentioned above is subject to some restrictions and+obligations imposed on the Licensee. Those obligations are the following:++Attribution right: The Licensee shall keep intact all copyright, patent or+trademarks notices and all notices that refer to the Licence and to the+disclaimer of warranties. The Licensee must include a copy of such notices and a+copy of the Licence with every copy of the Work he/she distributes or+communicates. The Licensee must cause any Derivative Work to carry prominent+notices stating that the Work has been modified and the date of modification.++Copyleft clause: If the Licensee distributes or communicates copies of the+Original Works or Derivative Works, this Distribution or Communication will be+done under the terms of this Licence or of a later version of this Licence+unless the Original Work is expressly distributed only under this version of the+Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee+(becoming Licensor) cannot offer or impose any additional terms or conditions on+the Work or Derivative Work that alter or restrict the terms of the Licence.++Compatibility clause: If the Licensee Distributes or Communicates Derivative+Works or copies thereof based upon both the Work and another work licensed under+a Compatible Licence, this Distribution or Communication can be done under the+terms of this Compatible Licence. For the sake of this clause, ‘Compatible+Licence’ refers to the licences listed in the appendix attached to this Licence.+Should the Licensee's obligations under the Compatible Licence conflict with+his/her obligations under this Licence, the obligations of the Compatible+Licence shall prevail.++Provision of Source Code: When distributing or communicating copies of the Work,+the Licensee will provide a machine-readable copy of the Source Code or indicate+a repository where this Source will be easily and freely available for as long+as the Licensee continues to distribute or communicate the Work.++Legal Protection: This Licence does not grant permission to use the trade names,+trademarks, service marks, or names of the Licensor, except as required for+reasonable and customary use in describing the origin of the Work and+reproducing the content of the copyright notice.++6. Chain of Authorship++The original Licensor warrants that the copyright in the Original Work granted+hereunder is owned by him/her or licensed to him/her and that he/she has the+power and authority to grant the Licence.++Each Contributor warrants that the copyright in the modifications he/she brings+to the Work are owned by him/her or licensed to him/her and that he/she has the+power and authority to grant the Licence.++Each time You accept the Licence, the original Licensor and subsequent+Contributors grant You a licence to their contributions to the Work, under the+terms of this Licence.++7. Disclaimer of Warranty++The Work is a work in progress, which is continuously improved by numerous+Contributors. It is not a finished work and may therefore contain defects or+‘bugs’ inherent to this type of development.++For the above reason, the Work is provided under the Licence on an ‘as is’ basis+and without warranties of any kind concerning the Work, including without+limitation merchantability, fitness for a particular purpose, absence of defects+or errors, accuracy, non-infringement of intellectual property rights other than+copyright as stated in Article 6 of this Licence.++This disclaimer of warranty is an essential part of the Licence and a condition+for the grant of any rights to the Work.++8. Disclaimer of Liability++Except in the cases of wilful misconduct or damages directly caused to natural+persons, the Licensor will in no event be liable for any direct or indirect,+material or moral, damages of any kind, arising out of the Licence or of the use+of the Work, including without limitation, damages for loss of goodwill, work+stoppage, computer failure or malfunction, loss of data or any commercial+damage, even if the Licensor has been advised of the possibility of such damage.+However, the Licensor will be liable under statutory product liability laws as+far such laws apply to the Work.++9. Additional agreements++While distributing the Work, You may choose to conclude an additional agreement,+defining obligations or services consistent with this Licence. However, if+accepting obligations, You may act only on your own behalf and on your sole+responsibility, not on behalf of the original Licensor or any other Contributor,+and only if You agree to indemnify, defend, and hold each Contributor harmless+for any liability incurred by, or claims asserted against such Contributor by+the fact You have accepted any warranty or additional liability.++10. Acceptance of the Licence++The provisions of this Licence can be accepted by clicking on an icon ‘I agree’+placed under the bottom of a window displaying the text of this Licence or by+affirming consent in any other similar way, in accordance with the rules of+applicable law. Clicking on that icon indicates your clear and irrevocable+acceptance of this Licence and all of its terms and conditions.++Similarly, you irrevocably accept this Licence and all of its terms and+conditions by exercising any rights granted to You by Article 2 of this Licence,+such as the use of the Work, the creation by You of a Derivative Work or the+Distribution or Communication by You of the Work or copies thereof.++11. Information to the public++In case of any Distribution or Communication of the Work by means of electronic+communication by You (for example, by offering to download the Work from a+remote location) the distribution channel or media (for example, a website) must+at least provide to the public the information requested by the applicable law+regarding the Licensor, the Licence and the way it may be accessible, concluded,+stored and reproduced by the Licensee.++12. Termination of the Licence++The Licence and the rights granted hereunder will terminate automatically upon+any breach by the Licensee of the terms of the Licence.++Such a termination will not terminate the licences of any person who has+received the Work from the Licensee under the Licence, provided such persons+remain in full compliance with the Licence.++13. Miscellaneous++Without prejudice of Article 9 above, the Licence represents the complete+agreement between the Parties as to the Work.++If any provision of the Licence is invalid or unenforceable under applicable+law, this will not affect the validity or enforceability of the Licence as a+whole. Such provision will be construed or reformed so as necessary to make it+valid and enforceable.++The European Commission may publish other linguistic versions or new versions of+this Licence or updated versions of the Appendix, so far this is required and+reasonable, without reducing the scope of the rights granted by the Licence. New+versions of the Licence will be published with a unique version number.++All linguistic versions of this Licence, approved by the European Commission,+have identical value. Parties can take advantage of the linguistic version of+their choice.++14. Jurisdiction++Without prejudice to specific agreement between parties,++- any litigation resulting from the interpretation of this License, arising+  between the European Union institutions, bodies, offices or agencies, as a+  Licensor, and any Licensee, will be subject to the jurisdiction of the Court+  of Justice of the European Union, as laid down in article 272 of the Treaty on+  the Functioning of the European Union,++- any litigation arising between other parties and resulting from the+  interpretation of this License, will be subject to the exclusive jurisdiction+  of the competent court where the Licensor resides or conducts its primary+  business.++15. Applicable Law++Without prejudice to specific agreement between parties,++- this Licence shall be governed by the law of the European Union Member State+  where the Licensor has his seat, resides or has his registered office,++- this licence shall be governed by Belgian law if the Licensor has no seat,+  residence or registered office inside a European Union Member State.++Appendix++‘Compatible Licences’ according to Article 5 EUPL are:++- GNU General Public License (GPL) v. 2, v. 3+- GNU Affero General Public License (AGPL) v. 3+- Open Software License (OSL) v. 2.1, v. 3.0+- Eclipse Public License (EPL) v. 1.0+- CeCILL v. 2.0, v. 2.1+- Mozilla Public Licence (MPL) v. 2+- GNU Lesser General Public Licence (LGPL) v. 2.1, v. 3+- Creative Commons Attribution-ShareAlike v. 3.0 Unported (CC BY-SA 3.0) for+  works other than software+- European Union Public Licence (EUPL) v. 1.1, v. 1.2+- Québec Free and Open-Source Licence — Reciprocity (LiLiQ-R) or Strong+  Reciprocity (LiLiQ-R+).++The European Commission may update this Appendix to later versions of the above+licences without producing a new version of the EUPL, as long as they provide+the rights granted in Article 2 of this Licence and protect the covered Source+Code from exclusive appropriation.++All other changes or additions to this Appendix require the production of a new+EUPL version.
