Choice of XML Parsers
- SECURE_XML - less prone to exploits.
- QUASI_XML - allows flexible character set for object names.
- STANDARD_XML - the old standby.
Path Normalization
>>> c = [ "/", zone, './home/', user ]
>>> session.query(Collection).filter(Like(Collection.name,
iRODSPath(*c,'%'))

We can now:
- login in as the anonymous user, without a password
- use ticket access as the anonymous user
- use long PAM login tokens > 1024 characters
- access ticket and metadata APIs using ADMIN_KW
- use the full checksum API in 4.2.11, 4.3.0
- get owner, timestamp, inheritance via Collection attributes
- change own password (or others' passwords as admin)
Python iRODS Client Library - Future Work
- improve parallel transfer performance
- allow relative object paths and cwd context for sessions
- continue working towards full coverage of the iRODS API
