  2. Agenda • Index Object Schema • The Problem • Crawler Policy • TIO schema • Proposal • Replication infrastructure • Registration of server • TIO distribution

  3. Index Object Schema: The problem • Plan to set up an index based European White Pages service • How to define which data to crawl • How to tokenize the data

  4. Crawler Policy • Crawler visits only registered server • Crawler binds to server to authenticate • Server admin can define crawlable data: • via access control mechanisms • via a special entry that acts like robots.txt • Crawler can be configured to only crawl specific entries (defined by Objectclass) and/or attributes

  5. TIO Schema version: x-tagged-index-1 updatetype: total thisupdate: 958081068 BEGIN IO-Schema createtimestamp: FULL labeleduri: FULL sn: FULL postaladdress: FULL cn: TOKEN title: FULL facsimiletelephonenumber: FULL dn: FULL mail: FULL telephonenumber: FULL objectclass: FULL personaltitle: FULL version: FULL street: FULL o: FULL END IO-Schema

  6. TIO schema (contd.) • Can be defined in LDIF output • Can be defined by TIO conversion programm (“TIO Collapser”)

  7. Proposal for a European White and Yellow pages service • Search only for objectclass=person, organization or organizationalUnit • Include only the following attributes into the TIO • sn FULL • cn TOKEN • o TOKEN (person: only in InetOrgPerson) • ou TOKEN (person: only in InetOrgPerson) • mail RFC822 • c FULL • l TOKEN
