  1. Module 15 Object and Content Relationships (Supplemental)

  2. Module Objectives • Describe the purpose of the dmr_content object • List the different types of object-contentrelationships • Describe how renditions are associatedwith an object • Describe how content is managed whenobjects are versioned • Explain how a version tree is maintained • Explain how objects are associated withpermission sets Object and Content Relationships

  3. What is a Content File? • Content Files • Object-Content Relationships • Version Relationships • Permission Set Relationships • A content file • Can be text, graphics, images and other information that make up an object • Can be of formats including HTML, XML, and XSL • Is linked with any subtype of dm_sysobject (except folders and cabinets) such as dm_document • Information about the format and location of a content file is contained in the dmr_content object dmr_content dm_sysobject (metadata) content file Object and Content Relationships

  4. The dmr_content Object • Links the object to the content file • Is a read-only object that users and applications may query Object and Content Relationships

  5. dm_ sysobject: Content-related Properties Object and Content Relationships

  6. dm_sysobject and dmr_content • Content Files • Object-Content Relationships • Version Relationships • Permission Set Relationships • There are several possible relationshipsbetween SysObjects and content files: One SysObject / rendition(s) as content files One SysObject / one content file One SysObject / many content files (multi-page) Object and Content Relationships

  7. One SysObject / One Content File Repository dm_document content file r_object_id = 09000001800bcc8f i_contents_id = 0600000180015e18r_page_cnt = 1 dmr_content r_object_id = 0600000180015e18parent_id[0] = 09000001800bcc8f page[0] = 0 Object and Content Relationships

  8. Useful Queries: Objects and Content • Retrieve information about a specific content file: • Which objects depend on a specific content file: select r_object_id, parent_id, page, rendition, content_size, set_time, set_client, set_file from dmr_content where any parent_id = '090009dd800039a4' select r_object_id, object_name, a_content_type, r_object_type, r_lock_owner, r_link_cnt from dm_sysobject where i_contents_id = ‘0600030980000c78’ Object and Content Relationships

  9. One SysObject / Many Content Files • i_contents_id references only the first page: dm_document r_object_id = 09000001800bcc8fi_contents_id = 0600000180015e18r_page_cnt = 3 dmr_content r_object_id = 0600000180015e18parent_id[0] = 09000001800bcc8fpage[0] = 0 dmr_content r_object_id = 0600000180015e1aparent_id[0] = 09000001800bcc8fpage[0] = 1 dmr_content r_object_id = 0600000180015e1bparent_id[0] = 09000001800bcc8fpage[0] = 2 Object and Content Relationships

  10. Useful Queries: Multiple Content Files • How many content files are associated witha specific object: • What are the object IDs of the content objectsassociated with a specific object: select r_page_cnt from dm_document where r_object_id = ‘09000001800bcc8f’ select r_object_id from dmr_content where any parent_id = ‘09000001800bcc8f’ Object and Content Relationships

  11. One SysObject / Rendition(s) • Each rendition file is stored as a separate content object dm_document r_object_id = 09000001800bcc8fi_contents_id = 0600000180015e18 a_content_type = msw6 dmr_content dmr_content r_object_id = 0600000180015e18 parent_id[0] = 09000001800bcc8f page[0] = 0rendition = 0full_format = msw8 r_object_id = 0600000180015e20parent_id[0] = 09000001800bcc8fpage[0] = 0rendition = 2full_format = pdf rendition property 0=original content 1=server generated 2 =client generated Object and Content Relationships

  12. Useful Queries: Renditions • Display all objects that have renditions: • Display all of my objects that have PDF renditions: select r_object_id, object_name, a_content_type, r_object_type,r_lock_owner, r_link_cnt from dm_document where r_object_id in (select parent_id from dmr_content where rendition > 0) select r_object_id, object_name, a_content_type, r_object_type, r_lock_owner, r_link_cnt from dm_document where r_object_id in (select parent_id from dmr_content where full_format='pdf’ and rendition > 0) and owner_name = user Object and Content Relationships

  13. Versioning Content • Content Files • Object-Content Relationships • Version Relationships • Permission Set Relationships Check in as New Version Save as Same Version version 1.0 version 1.1 version 1.0 dm_document dm_document dm_document dmr_content dmr_content dmr_content dmr_content Many SysObjects / Many Content Files One SysObject / Many Content Files Object and Content Relationships

  14. Version Relationships r_object_id = 09000001800a327b i_antecedent_id = 0000000000000000 i_chronicle_id = 09000001800a327b i_direct_desc = 1 i_latest_flag = 0 version 1.0 dm_document i_antecedent_id = 09000001800a327b i_chronicle_id = 09000001800a327b r_object_id = 09000001800bcc8f i_direct_desc = 1 i_latest_flag = 0 version 1.1 dm_document i_antecedent_id = 09000001800bcc8f i_chronicle_id = 09000001800a327b r_object_id = 09000001800bd1a3 i_direct_desc = 0 i_latest_flag = 1 version 2.0 dm_document Object and Content Relationships

  15. Permission Set Relationships • Permission sets are associated with objects through theacl_name and acl_domain attributes of the SysObject: dm_document acl_name = internal_reviewersacl_domain = sdalton dm_acl owner_name = sdaltonobject_name = internal_reviewers Object and Content Relationships

  16. Test Your Knowledge • Content Files • Object-Content Relationships • Version Relationships • Permission Set Relationships • True/False: SysObjects are related tocontent files through the dmr_contentobject. • True/False: Rendition content files are maintainedby the dmr_rendition object. • Which of these operations adds a new content file to the repository not a new SysObject:A) Create a new versionB) Create a renditionC) Save as the same versionD) Add a component to a virtual document Object and Content Relationships

  17. Classroom Exercise: Lab 15 • During the exercise, you will: • Issue DQL queries to gain informationabout object and content relationships • Issue DQL queries to gain informationabout renditions Object and Content Relationships
