+* Difficulty to implement the rule: easy

+## Quality Attribute

+* Maintainability
+
+## Rule Description
+
+Description from Massé [1].
+
+To make your URIs easy for people to scan and interpret, use the hyphen (-) character
+to improve the readability of names in long path segments. Anywhere you would use
+a space or hyphen in English, you should use a hyphen in a URI.
+
+## Implemented
+
+* Yes
+
+## Implementation Details (Issue #13)
+
+* Static implementation
+* Check if a path segment can be reduced to more than one word. If yes and the path segment does not contain (-) hyphens, there is a violation
+* Give the hint to use hyphens to separate words in a path segment
+
+### What is checked:
+* extract path segments from path using "/" as delimiter
+* based on an English dictionary, the extracted path is checked for substrings. If one or more substrings are found, there is a violation of the rule
+* pathSegment can be camelCase, kebabCase, snakeCase, all lowercase, all uppercase, or just a mixture of these
+
+### What is not checked:
+* presence of invalid delimiters
+* check of dynamic parameters
+
+### Future work
+
+* None

+
+## Rule Description
+
+Description from Massé [1].
+
+When convenient, lowercase letters are preferred in URI paths since capital letters can
+sometimes cause problems. RFC 3986 defines URIs as case-sensitive except for the
+scheme and host components.
+
+## Implemented
+
+* Yes
+
+## Implementation Details (Issue #10)
+
+* Static implementation
+* Check path if it contains an uppercase letter, if so give a warning
+* Give the hint to use lowercase letters instead of uppercase
+
+### What is checked:
+* check if the path contains an uppercase letter
+* check if the path is empty or there are no paths
+
+### What is not checked:
+* presence of invalid delimiters
+* check of dynamic parameters
+
+### Future work
+
+* None
