| 2 | # This example demonstrates using an oset (object set) to control access |
|---|
| 3 | # to files based on the attributes of the principals. The script creates |
|---|
| 4 | # three principals League, John and Mark and sets out the access policy. |
|---|
| 5 | # |
|---|
| 6 | # files are named by URNs and are not principals. |

| 7 | # |
|---|
| 8 | # A principal's access rights are controlled by the League principal. If a |
|---|
| 9 | # principal has the role role::stadium(string:'access',boolean:true,time:now) |
|---|
| 10 | # that principal can go into stadium if principal's team has a scheduled |
|---|
| 11 | # gametime. A principal is in team's roster if it is in |
|---|
| 12 | # the oset of players(team) defined by League, written |
|---|
| 13 | # [keyid:League].oset:players(string:'north')) |
|---|
| 14 | # |
|---|
| 15 | # The file, attr.py, lays out the policy that players of a given team can |
|---|
| 16 | # go to the stadium when it is their team's gametime -- credential 1. |
|---|
| 17 | # or any player of a team that is controlled by the League principal can |
|---|
| 18 | # go to the stadium during stadium's free for all time -- credential 2. |
|---|
| 19 | # |
|---|
| 20 | # Credentials 3 & 4 establish the afernoon gametimes for team(north) |
|---|
| 21 | # and for team(south) |
|---|
| 22 | # Credentials 5 & 6 establish John as player of team(north) and Mark as |
|---|
| 23 | # a player for team(south) |
|---|
| 24 | # |
|---|
| 25 | # The query.py file runs 3 queries. First it confirms that John can |
|---|
| 26 | # go to stadium at his team's gametime, then it confirms that Mark cannot |
|---|
| 27 | # go because it is not his gametime, but Mark can go to the stadium during |
|---|
| 28 | # stadium's free-for-all early morning time |
