It's sometimes useful to extract File System metadata from files that people often see when browsing a file on an operating system.
- POSIX permissions
- Datetime stamps, including: lastModified, creationTime, lastAccessTime
- Is a symbolic file?
- Is a directory?
- File owner
- Is hidden file?
Java 7's Files.getAttributes  does this in a platform-generic way. We should leverage this and add an extractor for the benefit of the community.
