Which MIME types are related to file extension ".obo"?
The .obo file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .obo Files
OBO files are plain text documents that use the PSI MI format for storing structured data on molecular interactions.
They hold text-based information following standardized rules, which makes the data easy to read and share.
- Format: They use the text/plain MIME type, meaning they are simple text files.
- Standard: The PSI MI format is a specification used to describe molecular interactions in bioinformatics.
- Usage: These files are common in research for exchanging and annotating biological interaction data.
- Software Support: They can be opened with basic text editors like Notepad or more advanced tools such as OBO-Edit and Protege that help manage ontologies.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .obo file?
An .obo file is a structured text document used primarily in bioinformatics to store ontologies and molecular interaction data. It follows a specific standard (often associated with the Open Biological and Biomedical Ontology or PSI MI format) to describe relationships between biological terms in a human-readable format.
How do I open an .obo file?
You can open these files using specialized ontology editors like OBO-Edit or Protégé for a visual representation of the data. Because they are plain text, they can also be viewed and edited in standard tools like Notepad, Notepad++, or TextEdit.
Can I convert an OBO file to OWL or JSON?
Yes, OBO files are frequently converted to OWL (Web Ontology Language) or JSON for broader compatibility with web tools. Software such as OBO-Edit or command-line tools like ROBOT can perform these conversions efficiently.
Why does my computer identify the .obo file as a text document?
Operating systems recognize the file structure as plain text regardless of the extension. This is why the MIME type is often set to text/plain, allowing the system to open it with default text readers.
Is it safe to open .obo files?
Yes, .obo files are non-executable text files, meaning they cannot run code or install viruses on their own. However, as with any downloaded data, you should ensure the file originates from a trusted scientific repository.
What should I do if the OBO file is not readable in Notepad?
If the raw text is too complex or lacks line breaks, the file is best viewed in dedicated software like OBO-Edit. These tools parse the structured data and display it as an interactive tree or graph, making it much easier to understand than the raw code.
General 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 can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
