+Metadata Specification
+======================
+
+This is Metadata Specification which defines that all data needed
+for test execution in the CI system are stored as a plain text
+information in Flexible Metadata Format under version control in
+the git repository close to the test code or source code. FMF uses
+YAML to store data in a concise human and machine readable way
+plus adds a few nice features like virtual hierarchy, inheritance
+and elasticity to minimize data duplication and maintenance. There
+are two levels of metadata defined:
+
+**L1 Metadata**
+
+These are test metadata closely related to individual test cases
+for which it make sense to store them directly with the test code.
+Examples of such metadata are summary, description, duration or
+tags. See Level 1 Metadata section for more detailed information
+and list of already defined attributes.
+
+**L2 Metadata**
+
+These metadata contain information for execution of multiple test
+cases such as how the environment for testing should be prepared,
+which set of test cases is relevant for testing specific artifact
+or which frameworks should be used for execution. See Level 2
+Metadata section for detailed specification.
