What is MIME type "application/vnd.oasis.opendocument.chart-template"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type application/vnd.oasis.opendocument.chart-template designates a chart template in the OpenDocument family.
It marks files that serve as blueprints for creating chart documents without starting from scratch.
Files using this type typically carry the OTC extension.
When an application loads a file of this kind, it applies predefined design settings for chart elements such as colors, fonts, gridlines, and layout.

Main use: Enables consistent chart styling across multiple documents.
Key feature: Stores preset design elements to speed up the chart-creation process.
Practical functionality: Acts as a reusable design framework in office suites that follow the OpenDocument standard.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
