NAME

AddressBook::Config - AddressBook configuration object

CONTENTS

SYNOPSIS

The AddressBook::Config object contains the list of cannonical attribute names, their respective backend database equivalents, attribute metadata, and backend database attributes.



  $config = AddressBook::Config->new(config_file=>$filename);



AddressBook::Config looks for a configuration file in /etc/AddressBook.conf if no config_file parameter is present.

DESCRIPTION

Configuration is read from an XML configuration file which follows this DTD:



  <?xml version="1.0"?>
  <!DOCTYPE AddressBook_config [
    <!ELEMENT fields (field)>
    <!ELEMENT field  (db)>
    <!ELEMENT db (EMPTY)>

    <!ELEMENT LDIF (EMPTY)>
    <!ELEMENT DBI (EMPTY)>
    <!ELEMENT PDB (EMPTY)>

For example,



  <AddressBook_config>
    <fields>
      <field name="firstname" type="text" order="1">
        <db type="LDAP" name="givenname" />
        <db type="HTML" name="First Name" order="2" />
      </field>
      <field name="lastname" type="text" order="2">
        <db type="LDAP" name="sn" />
        <db type="HTML" name="Last Name" order="1" />
      </field>
      <field name="fullname" type="text" order="3"
             calculate="$firstname .   . $lastname">
        <db type="LDAP" name="cn" />
        <db type="HTML" name="Full Name" />
      </field>
    </fields>
    <databases>
      <LDAP objectclass="inetOrgPerson"
            base="o=abook"
            dn_calculate="cn=.$cn"
            username="cn=Manager,o=abook"
            password="secret"
            key_fields="cn"
      />
    </databases>
  </AddressBook_config>



This defines three attributes with cannonical names firstname, lastname, and fullname. These are accessed in the LDAP backend context as givenname, sn and cn, and in the HTML backend context as First Name, Last Name and Full Name respectively.

The default attribute ordering is firstname, lastname, fullname, however the HTML backend overrides this and in that context attributes are ordered: lastname, firstname, fullname. All other meta-attributes may be similarily overriden by specific backends

fullname is a calculated attribute. Calculation strings may reference the names of other attributes by $<attr_name>.

Backend databases may also be named and then tied to a source type by using the ’driver’ attribute. This technique is useful for defining multiple backends of the same type. For example,



  <AddressBook_config>
    <fields>
      <field name="firstname" >
        <db type="ldap_server_1" name="givenname" />
        <db type="ldap_server_2" name="givenname" />
      </field>
      <field name="lastname" >
        <db type="ldap_server_1" name="sn" />
        <db type="ldap_server_2" name="sn" />
      </field>
    </fields>
    <databases>
      <ldap_server_1 driver="LDAP"
                     hostname="server_1"
                     objectclass="inetOrgPerson"
                     base="o=abook"
                     dn_calculate="cn=.$cn"
                     username="cn=Manager,o=abook"
                     password="secret"
                     key_fields="cn"
      />
      <ldap_server_2 driver="LDAP"
                     hostname="server_2"
                     objectclass="inetOrgPerson"
                     base="o=abook"
                     dn_calculate="cn=.$cn"
                     username="cn=Manager,o=abook"
                     password="secret"
                     key_fields="cn"
      />
    </databases>
  </AddressBook_config>



See the various backend man pages for information on the <database> configuration attributes. See also the sample configuration files in the ’examples’ directory.

    getMeta



  %meta = %{$config->getMeta(attr=>$attr)}
  %meta = %{$config->getMeta(attr=>$attr,db=>$db)}



Returns an attribute metadata hash
