About .iso19139 Files
ISO19139 files are XML documents that store geospatial metadata following an international standard.
They use the MIME type text/iso19139+xml to signal that their content is XML-based.
- Geospatial metadata: They hold structured information about geographic data, such as spatial reference, data quality, and geographic extent.
- Standards compliance: They adhere to the ISO 19139 standard for geographic information metadata, ensuring consistency across systems.
- Data exchange: They allow different GIS applications and agencies to share detailed metadata safely and uniformly.
According to FilExt.com, ISO19139 files are widely used in geospatial contexts to facilitate clear and interoperable metadata management.
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 .iso19139 file?
An ISO19139 file is an XML document that stores geospatial metadata according to the ISO 19139 international standard. It contains structured details about geographic datasets, such as their spatial extent, coordinate reference systems, and data quality, allowing different GIS systems to exchange information accurately.
How do I open an .iso19139 file?
You can open these files using specialized GIS software like QGIS or ESRI ArcGIS, which can interpret the metadata tags visually. Because the file format is text-based XML, you can also view or edit the raw code using standard text editors like Notepad++, Sublime Text, or Visual Studio Code.
What is the correct MIME type for .iso19139 files?
The specific MIME type used to identify these files over the web is text/iso19139+xml. This subtype indicates that the file is an XML document conforming to the ISO 19139 schema. You can learn more about XML media types at mime-type.com.
Can I rename an .iso19139 file to .xml?
Yes, renaming the file extension to .xml is a common workaround to open it quickly in web browsers or generic XML viewers. However, keeping the original extension is useful for GIS software to automatically recognize the specific metadata standard being used.
How can I convert an ISO19139 file to HTML?
Many GIS tools include built-in functions to export metadata to human-readable HTML reports. Alternatively, because the file is XML, you can use an XSLT stylesheet designed for ISO 19139 to transform the raw data into a formatted web page.
Why does my computer not recognize this file extension?
The .iso19139 extension is specialized for the geospatial industry and is not a default file type on standard Windows or macOS installations. You may need to manually right-click the file and select "Open with..." to choose your text editor or GIS application.
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.
