What is MIME type "application/commonground"?

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

The application/commonground MIME type identifies files that belong to a specialized data format. They are not standard documents or images but are meant for a dedicated software environment known as Common Ground.

Applications use this MIME type to instruct your operating system how to handle these files properly. It tells your system that the file has structured data needing a specific tool for viewing or editing.

The main use is to store and manage configuration or structured data for Common Ground systems.
It supports controlled data exchange and proper processing within a dedicated software ecosystem.
It ensures that files are opened with compatible applications, preserving data integrity and functionality.

Files with this MIME type use the DP extension. This extension links directly to the file type associated with Common Ground data.

For additional insights into MIME types and their proper handling, see the IANA Application MIME Types page.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:


    Content-Type: application/commonground

HTML

In HTML, you can specify the MIME type in various elements:

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.
