Name: Johannes Wilm

Email: [email protected]

Media type name: application

Media subtype name: vnd.fiduswriter.template+zip

Required parameters: N/A.

Optional parameters: N/A.

Encoding considerations: binary

This media type is a ZIP container (indicated by the "+zip"
structured syntax suffix). The archive is transferred as binary data and
MUST NOT be encoded as text. In MIME e-mail contexts, transfer encoding
such as base64 is required.

Security considerations: Identical to those of application/vnd.fiduswriter+zip. A document
template is a ZIP container holding JSON template definitions and
template assets. Implementations MUST validate the "mimetype" and
"filetype-version" entries, bound decompression sizes, reject malformed
JSON, and treat template assets as untrusted data that is never executed.

Interoperability considerations: Same container convention as application/vnd.fiduswriter+zip: a first,
uncompressed "mimetype" entry puts the media type string at byte offset
38. Existing files carry the legacy string
"application/fidustemplate+zip", which is a deprecated alias; readers
SHOULD accept both strings.

Published specification: The Fidus Writer file container format specification (FORMAT.md), at
https://www.fiduswriter.org/spec/FORMAT.md, and the Fidus Writer
document-template format documentation.

Applications which use this media: 

- Fidus Writer, which exports and imports document templates
(.fidustemplate files); available in the online service and, from
version 5.0, in the desktop application.

- The Fidus Writer document-template editor
(@fiduswriter/document-template-editor).

Fragment identifier considerations: N/A.

Restrictions on usage: N/A.

Provisional registration? (standards tree only): No

Additional information:

1. Deprecated alias names for this type: application/fidustemplate+zip
2. Magic number(s): - "PK\003\004" (50 4B 03 04) at byte offset 0 (ZIP local file header), then - "application/fidustemplate+zip" or "application/vnd.fiduswriter.template+zip" at byte offset 38 (the content of the first, uncompressed "mimetype" archive entry).
3. File extension(s): fidustemplate
4. Macintosh file type code: N/A.
5. Object Identifiers: N/A.

General Comments: The media type describe the file format itself and are independent of how
the application is delivered: Fidus Writer 5.0 is distributed both as an
online service and as a desktop application, and `.fidustemplate` files are
interchangeable between them.
