Frequently asked questions

I did not receive the email with my credentials. What should I do?

Check your spam folder first. If nothing arrived, ask the Administrator or the Supervisor of your institution to verify your email address and resend the credentials.

I forgot my password.

Use the password-reset link on the login page: enter your email address and follow the instructions you receive by email.

Why can't I edit a certain artefact or model?

Editing rights depend on your role: Authors can edit the items they created, Supervisors every item of their own institution, Administrators everything. If the edit button is missing, the item belongs to another author or institution.

What file format do 3D models need?

The viewer uses the Nexus multiresolution format: upload files in compressed Nexus format (.nxz). Models in common formats (PLY, OBJ…) must first be converted with the free Nexus tools (nxsbuild + nxscompress) provided by the Visual Computing Lab, ISTI-CNR.

How big can a 3D model be?

Thanks to the multiresolution format there is no practical limit for visualisation — the model streams progressively. Mind, however, that very large files take longer to upload and consume server disk space; ask the administrator of your instance about local size policies.

What is the difference between metadata and paradata?

Metadata describe the object (author, owner, license, description). Paradata document the process that produced the digital object: acquisition technique, software, number of points/polygons, textures, scans and pictures used. Both are first-class citizens in the platform, because a digital replica is only as trustworthy as the documentation of how it was made.

Which licenses can I assign to content?

Content licensing uses open licenses: CC BY, CC0 and Public Domain. Each model and media item carries its own license, shown in its metadata.

Can I cite a model in a publication?

Yes. Models can carry a DOI and a citation string in their main data. The artefact and model pages are stable URLs and the metadata are exposed as machine-readable JSON-LD (CIDOC-CRM) through the public API.

What does "Under processing" mean?

New artefacts and models start in the Under processing state, meaning the record is still being worked on. Mark an item Complete when its documentation is ready. The dashboard filters items by this status, so unfinished records are easy to find.

What does "to connect" mean for a model?

A model that has been uploaded but not yet linked to an artefact. The dashboard model list has a dedicated filter to find them; open the model and connect it to the corresponding artefact.

Can I use the platform from a phone or tablet?

Yes, the interface adapts to mobile devices. For data entry and 3D model inspection a desktop browser is recommended.

Who do I contact for problems?

For account or content issues, the Administrator of your instance. For bugs and feature requests, open an issue on the GitHub repository.
