What is MIME type "application/sparql-update"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
application/sparql-update is a MIME type for SPARQL update scripts used in RDF databases. It tells software that the file contains commands to change RDF data, like adding or removing triples. These commands follow the SPARQL standard defined by the W3C.- Primary use: Executes update operations on RDF stores through SPARQL endpoints.
- Commands included: Typically contains INSERT and DELETE statements.
- File association: Files using this MIME type usually have the RU extension.
- Functionality: Supports direct modifications to RDF graphs over HTTP.
This MIME type makes it easier to programmatically update semantic data stores. It ensures consistency across different systems handling RDF updates. For additional details on file types, check out the resources at FileXT.

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.
