Terms of Service

OpenRTI is an open-access platform for publishing, examining and citing Reflectance Transformation Imaging (RTI) data of cultural heritage objects in the browser. Members can sign in, upload RTI data from the browser and manage their own records. By using the site or creating an account you agree to these terms.

• An account is for one person. Sign in with ORCID, Google or a link sent to your email; there are no passwords.
• Keep access to your email and sign-in accounts secure; you are responsible for activity in your OpenRTI account.
• We may suspend an account that breaks these terms or endangers the service or other users.

• You keep all rights to what you upload. You confirm that you have the right to upload it and to publish it under the licence you choose.
• You choose the licence of each record from the Creative Commons licences; for an object held by a museum, CC BY-NC 4.0 is suggested and the record notes that reuse may also need the museum's permission. OpenRTI never assigns a licence automatically.
• You allow OpenRTI to store, process (for example to create viewing tiles), display and distribute your records as needed to run the service, within the licence and visibility you choose.
• You are responsible for any permission needed to document and publish an object, for example from the museum, collection or excavation authority.
• You are responsible for the information and data you upload, including any personal data they contain.
• You comply with the law of the place where the object is held or was found, including the permits needed for museum objects and excavation finds (in Türkiye, Law No. 2863 on the Protection of Cultural and Natural Property and the permits of the Ministry and the museum directorates).
• Descriptive information must be honest: do not enter an author, date, institution, DOI or licence that the source does not support.

Published data versions do not change, so that citations stay valid. New or reprocessed data is published as a new version. Corrections of a record's information never change its data or its link: they are dated, with the fields they changed, in the record's public history. You can keep a record private before publishing it, and hide a published record from your account page and show it again later; its link then says that it is temporarily unavailable. Permanent removal of a published record follows the complaints and removal procedure below.

• Do not upload unlawful content or content that infringes the rights of others.
• Do not try to break the security of the service, access other accounts, or disrupt the service (for example with automated requests at a harmful rate).
• Do not upload malware or files disguised as RTI data.

If you believe a record infringes rights, contains personal data, lacks a required permit or is otherwise unlawful, write to [email protected] with the record's link and your reasons.

• We may take the record off the site while the complaint is reviewed; its link then says that it is temporarily unavailable.
• We answer within 30 days.
• The member who uploaded the record is told and may respond.
• A record that is removed does not leave a bare error behind: its persistent link shows its title, data creator, publication and withdrawal dates and the reason for withdrawal, so citations do not lead to a bare error page.

Site texts are licensed under CC BY 4.0 and the software under the MIT licence. Artefact data is licensed per record, as shown on each record. A record's structured details (title, identifiers, object type, material, places, dates and citation data) are published under CC0 1.0 so that catalogues and aggregators can harvest them. Descriptions and references written for a record are published under CC BY 4.0; passages quoted, adapted or translated from publications keep their own rights and must cite their source. Neither extends to the data itself.

RTI is not a measured three-dimensional model. Enhanced views support interpretation and are not raw data. The service is provided ‘as is’, without warranty; it is not guaranteed to run without interruption or error. To the extent permitted by law, OpenRTI is not liable for damages arising from its use or from records published by users. You are responsible for claims made against OpenRTI because of content you uploaded in breach of these terms.

We may update these terms; the date of the latest version is shown at the top, and significant changes are announced on the site. How we handle personal data is described in the Privacy Policy. Questions: [email protected].
