Abstract

Various embodiments described herein provide systems, methods, software, and data structures to allow or prevent viewing of users and groups of users by other users and groups of users. Some such embodiments include retrieving a listing of members from a member database, defining a first subset of one or more members selected from the retrieved member listing, and designating the first member subset as visible to a second subset of one or more members when a member of the second member subset retrieves a member listing.

Claims

1. A system comprising:

at least one processor; and

at least one memory device to store a content item policy fulfillment module executable by the at least one processor of the system to;

receive, via a network interface device from a requesting client content viewing application, a policy request including user identity data and data identifying a policy assigned to a content item;

determine whether a user represented by the user identity data is associated with the identified policy as either a user or as a member of a defined group, the determining including performing a query against a database storing;

user records representative of system users;

group records defining groups;

group assignment records associating users to groups;

policy records defining content access policies assignable to items of electronic content, wherein a content access policy identifies one or more permitted and restricted user actions with regard to an item of electronic content when a user accesses the item of electronic content associated with the content access policy; and

user/group policy records associating a policy record to a user or group record; and

when the user is associated with the policy, retrieve a policy record as a function of the data identifying the policy, retrieve data representative of users and groups assigned to the retrieved policy record as a function of the data identifying the policy, and send, via the network interface device, the retrieved policy record and data representative of the users and groups assigned to the retrieved policy record to the requesting client content viewing application, the policy record including data that limits at least one ability of the user to perform at least one action in the requesting client content viewing application with regard to the item of content and at least one other user or group of users assigned to the retrieved policy record.

2. The system of claim 1, wherein the requesting client content viewing application is an application attempting to operate using the content item.

3. The system of claim 1, wherein the database further includes visible user/group records identifying users and groups viewable by users and groups.

4. The system of claim 3, further comprising:

a visible user/group module executable by the at least one processor of the system to;

receive, via the network interface device, a request for a listing of users and groups viewable by the user represented by the user identity data with regard to the content item;

retrieve a listing of users and groups viewable by the user from the database as defined by at least one policy record associated with the user and the content item; and

respond, via the network interface device, to the request by sending data representative of the retrieved listing, wherein the visible user/group module in retrieving only a listing of users and groups viewable by the user thereby limits an ability of the user/group assignment module to receive input modifying user/group policy records that associate a policy record to a user or group record.

5. The system of claim 4, wherein the visible user/group module is further executable by the at least one processor of the system to:

receive the request for and provide the viewable user and group listing with a user interface definition renderable by a computing device from which the request was received;

receive input to modify visible user/group records; and

store the received input to the modified visible user/group records of the database.

6. The system of claim 1, wherein the content item is a page description language document.

7. A method comprising:

receiving, via a network interface device from a requesting client content viewing application, a policy request including user identity data and data identifying a policy assigned to a content item;

determining whether the user represented by the user identity data is associated with the identified policy as either a user or as a member of a defined group, the determining including performing a query against a database storing;

user records representative of system users;

group records defining groups;

group assignment records associating users to groups;

policy records defining content access policies assignable to items of electronic content, wherein a content access policy identifies one or more permitted and restricted user actions with regard to an item of electronic content when a user accesses the item of electronic content associated with the content access policy; and

user/group policy records associating a policy record to a user or group record; and

when the user is associated with the policy, retrieving a policy record as a function of the data identifying the policy, retrieving data representative of users and groups assigned to the retrieved policy record as a function of the data identifying the policy, and sending, via the network interface device, the retrieved policy record and data representative of the users and groups assigned to the retrieved policy record to the requesting client content viewing application, the retrieved policy record including data that limits at least one ability of the user to perform at least one action in the requesting client content viewing application with regard to the item of content and at least one other user or group of users assigned to the retrieved policy record.

8. The method of claim 7, wherein the requesting client content viewing application is an application attempting to operate upon the content item.

9. The method of claim 7, wherein the database further stores data of visible user/group records identifying users and groups viewable by users and groups.

10. The method of claim 9, further comprising:

receiving, via the network interface device, a request for a listing of users and groups viewable by the user represented by the user identity data with regard to the content item;

retrieving, from the database, a listing of users and groups viewable by the user as defined by at least one policy record associated with the user and the content item; and

sending, via the network interface device in response to the request, data representative of the retrieved listing, wherein in retrieving only a listing of users and groups viewable by the user thereby limits an ability of the user/group assignment module to receive input modifying user/group policy records that associate a policy record to a user or group record.

11. The method of claim 10, further comprising:

receiving the request for and providing data of the viewable user and group listing;

receiving input to modify visible user/group records; and

storing the received input to the modified visible user/group records of the database.

12. The method of claim 7, wherein the content item is a page description language document.

13. A computer readable storage medium with instructions stored thereon that are executable by at least one processor of a computer to cause the computer to:

receive, via a network interface device from a requesting client content viewing application, a policy request including user identity data and

data identifying a policy assigned to a content item;

determine whether the user represented by the user identity data is associated with the identified policy as either a user or as a member of a defined group, the determining including performing a query against a database storing;

user records representative of system users;

group records defining groups;

group assignment records associating users to groups;

policy records defining content access policies assignable to items of electronic content, wherein a content access policy identifies one or more permitted and restricted user actions with regard to an item of electronic content when a user accesses the item of electronic content associated with the content access policy; and

user/group policy records associating a policy record to a user or group record; and

when the user is associated with the policy, retrieve a policy record as a function of the data identifying the policy, retrieve data representative of users and groups assigned to the retrieved policy record as a function of the data identifying the policy, and send the policy record and data representative of the users and groups assigned to the retrieved policy record, via the network interface device in response to the received policy request, the retrieved policy record including data that limits at least one ability of the user to perform at least one action with regard to the item of content and at least one other user or group of users assigned to the retrieved policy record.

14. The computer readable storage medium of claim 13, wherein the requesting client content viewing application is an application attempting to operate upon the content item.

15. The computer readable storage medium of claim 13, wherein the database further stores data of visible user/group records identifying users and groups viewable by users and groups.

16. The computer readable storage medium of claim 15, with further instructions stored thereon that are executable by the at least one processor to cause the computer to:

receive, via the network interface device, a request for a listing of users and groups viewable by the user represented by the user identity data with regard to the content item;

retrieve, from the database, a listing of users and groups viewable by the user as defined by at least one policy record associated with the user and the content item; and

send, via the network interface device in response to the request, data representative of the retrieved listing, wherein in retrieving only a listing of users and groups viewable by the user thereby limits an ability of the user/group assignment module to receive input modifying user/group policy records that associate a policy record to a user or group record.

17. The computer readable storage medium of claim 13, wherein the content item is a page description language document.
