Resource Description Framework Format

What is RDF file?

RDF file is a document file used for defining data related to resources on the web. RDF file contains metadata such as website map, page descriptions, keywords or update logs.

RDF file characteristics

RDF format specification was created by World Wide Web Consortium (W3C). RDF document files are written in Resource Description Framework language. RDF are used to share information with applications in order for them to process it.

RDF file structure

RDF document uses XML syntax to store data. XML format is used due to its simplicity regarding data representation model. The model describes data using 3 different expressions:

  1. Subject – defines the resource,

  2. Predicate – defines traits/aspects,

  3. Object – stores values of predicate.

Other uses of RDF files

Besides representing information about web resources, RDF files are used in Mozilla Firefox for different purposes. For example, they can be used to store window settings or toolbar configuration data.

How to open file with RDF extension?

Problems with accessing RDF may be due to various reasons. Fortunately, most common problems with RDF files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The list below will guide you through the process of addressing the encountered problem.

Step 1. Download and install Mozilla SeaMonkey

Install software to open RDF file The main and most frequent cause precluding users form opening RDF files is that no program that can handle RDF files is installed on user’s system. The most obvious solution is to download and install Mozilla SeaMonkey or one to the listed programs: Adobe Dreamweaver, XMLSpy, NotePad++ text editor. Above you will find a complete listing of programs that support RDF files, classified according to system platforms for which they are available. One of the most risk-free method of downloading software is using links provided by official distributors. Visit Mozilla SeaMonkey website and download the installer.

Step 2. Check the version of Mozilla SeaMonkey and update if needed

Update software that support file extension RDFIf you already have Mozilla SeaMonkey installed on your systems and RDF files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. This can be one of the causes why RDF files are not compatible with Mozilla SeaMonkey. The most recent version of Mozilla SeaMonkey is backward compatible and can handle file formats supported by older versions of the software.

Step 3. Set the default application to open RDF files to Mozilla SeaMonkey

After installing Mozilla SeaMonkey (the most recent version) make sure that it is set as the default application to open RDF files. The process of associating file formats with default application may differ in details depending on platform, but the basic procedure is very similar.

Step 4. Ensure that the RDF file is complete and free of errors

If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the RDF file in question. It is probable that the file is corrupted and thus cannot be accessed.

Check RDF file for viruses
1. Verify that the RDF in question is not infected with a computer virus

If the file is infected, the malware that resides in the RDF file hinders attempts to open it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the scanner detected that the RDF file is unsafe, proceed as instructed by the antivirus program to neutralize the threat.

2. Verify that the RDF file’s structure is intact

If the RDF file was sent to you by someone else, ask this person to resend the file to you. During the copy process of the file errors may occurred rendering the file incomplete or corrupted. This could be the source of encountered problems with the file. When downloading the file with RDF extension from the internet an error may occurred resulting in incomplete file. Try downloading the file again.

3. Ensure that you have appropriate access rights

Some files require elevated access rights to open them. Switch to an account that has required privileges and try opening the Resource Description Framework Format file again.

4. Make sure that the system has sufficient resources to run Mozilla SeaMonkey

If the system is under havy load, it may not be able to handle the program that you use to open files with RDF extension. In this case close the other applications.

5. Verify that your operating system and drivers are up to date

Latest versions of programs and drivers may help you solve problems with Resource Description Framework Format files and ensure security of your device and operating system. It may be the case that the RDF files work properly with updated software that addresses some system bugs.
