Approaches to Using the acl Element

There are two approaches to using the

acl

element:

• As the child of a

group

element

• As the child of a

record

element

If the

acl

element is the child of a

group

element, the

url

attribute is required. An

acl

element as the

child of a

group

element can be used in the following scenarios:

• Updating the ACL of a record (independently of content) for a URL that was previously fed with

attached ACLs.

• Modeling entities, such as folders, that would not otherwise be represented in the system.

If the

acl

element is the child of a

record

element, the

url

attribute is illegal. In this approach, the ACL

is immediately associated with the document.

Google does not recommend mixing the two approaches to using an

acl

element for a given URL in the

same feed.

Example Feed with an acl Element

The following code shows an example of a feed XML file with an

acl

element that inherits permissions.

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE gsafeed PUBLIC "-//Google//DTD GSA Feeds//EN" "gsafeed.dtd">

<datasource>TestUrlAcl</datasource>

<feedtype>incremental</feedtype>

</header>

<acl url="http://dummyhost.corp.google.com/" inheritance-type=”child-overrides”

inherit-from="http://corp.google.com/">

<principal scope="user" access="permit">edward</principal>

<principal scope="user" access="deny">william</principal>

<principal scope="group" access="permit">nobles</principal>

<principal scope="group" access="deny">playwrights</principal>

</acl>

<!-- Other acl elements or group elements with records can appear in any order in

this file -->
