What is XSD file?

XSD file contains formal description of XML document elements data definitions saved in XML text format. XSD file contains set of rules which a XML files must follow to be considered a proper XML file. The file doesn’t have an unique Internet Media Type identifire as it is the same type as XML - ‘a pplication/xml’ or ‘ text/xml’. XSD file can have its data organized into so called namespaces. Main schema components are:

  • Element declarations,
  • Attribute declarations,
  • Data types – simple or complex, based on restrictions, selection list, or primitive types,
  • Macros, that is reusable groups of elements or attributes,

XSD specification was developed in 2001 with the help of W3C (World Wide Web Consortium) organization. XSD format offers more features than similar DTD document defi n ition format. XSD specification document is divided into 3 parts:

  • Part 0. Primer contains general description of the standard and basics, commonly consulted by less technical users working with XSD,
  • Part 1. Structures,
  • Part 2. Datatypes.

Parts 1 and 2 are many pages long and written in technical language. Second version of the specification was released in 2004, and XSD 1.1 has been approved by W3C in 2012. XSD files are used for storing metadata for XML documents, but they can also by used by developers for generating code or document descriptions in human-readable form.

What else may cause problems?

There can be more reasons which determine that you are not able to open the XSD file (apart from the lack of the proper application installed).

First - the XSD file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the XSD file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the XSD file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the XSD file has not been completed and it cannot be opened properly).
