What is MIME type "application/vnd.openxmlformats-officedocument.vmldrawing"?

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

application/vnd.openxmlformats-officedocument.vmldrawing defines a drawing part that uses Vector Markup Language (VML) for vector graphics. It stores drawing instructions in XML code.

This format is part of the Office Open XML standard. It is used to embed scalable, high-quality vector images into documents. The drawings can include shapes, connectors, and other visual elements that adjust smoothly when resized.

Office Document Integration: Embeds vector graphics in documents created with modern office applications.
XML-Based Definition: Uses tag-based syntax that is similar in structure to HTML.
Scalability: Ensures images do not lose clarity regardless of zoom level.

Files that incorporate this drawing format can use types such as HTML or HTM.

For more technical details, refer to the IANA Media Type Registry or check out the Wikipedia entry on VML.

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.
