Alfresco tech talk live share extensibility metadata and actions for 4.1
- 1. Alfresco Share 4.1 Custom Metadata and Actions Mike Farman
- 2. Objectives • Extend Share without deep knowledge of how Share is built • Avoid copy-paste of existing code • Simplify ungraded – avoid diff/merge • Easier Deployment
- 3. Customizing the Document Library • Metadata • Actions … with configuration - no code
- 4. Custom Metadata Display • Control the metadata that is displayed in the Document List o e.g. Title, Status, EXIF Props etc • Supports OOTB and custom model properties • Config driven, no coding required o Optional Label o Property only displayed if present on node o Can use client-side JS for advanced rendering
- 5. Out-of-the-box Configuration • webapps/share/WEB-INF/classes/alfresco/ share-documentlibrary-config.xml • Templates • webapps/share/WEB-INF/classes/alfresco/ slingshot-documentlibrary-context.xml • Evaluators
- 6. Extend/Override • shared/classes/alfresco/web-extension share-config-custom.xml o Override existing o Add new templates • shared/classes/alfresco/web-extension custom-slingshot-context.xml • Custom evaluators
- 7. Example Metadata Template • Config: shared/classes/alfresco/web-extension/ share-config-custom.xml • Template ID: exif • Add line index 60 – exif_model with label • Evaluator o Reusing evaluator.doclib.indicator.exifMetadata from the core
- 8. Document Library Actions • Simplified & consolidated config for actions available on the DocLib, DocDetails and FolderDetails pages • Single Configuration File for OOTB Actions o share-documentlibrary-config.xml • Can be overridden via extensions o Add New, Remove Existing, Change Order of UI Actions o share-config-custom.xml • Actions Groups and Actions o Similar approach to Explorer
- 9. Out-of-the-Box Actions & ActionGroups • Like metadata, OOTB Actions defined in: o share/WEB-INF/classes/alfresco/share-documentlibrary-config.xml • <actions> section defines the individual actions • <actionGroups> defines where and the order in which they appear o Note: Action must be in an ActionGroup to appear • Extend/Override in share-config-custom.xml i.e.: o shared/classes/alfresco/web-extensions/share-config-custom.xml o No need to copy full OOTB Action/ActionGroup definitions
- 10. Example: Removing Existing Actions • share-config-custom.xml Config applies to DocLibActions Start Workflow Action ID disableAction Evaluator Upload New Version Action ID After: Before:
- 11. Adding New Actions • Configuration only, no coding required • 2 types of action: Simple and Advanced • Simple Action: No user input (i.e. dialog) o e.g. Extract Metadata o Returns success or failure message • Advanced Action: User provides parameters for action o e.g. Transform – Need to select target format and output location o Uses Forms service define dialogs • see share-form-config.xml for OOTB definitions o Can plug in your own actions and forms • Can be used to execute the OOTB Actions or your own custom actions
- 12. Example New Action: Import ACP/ZIP • share-config-custom.xml Action Definition Form Definition - Select destination for extracted files
- 13. Controlling when actions are available • Evaluators o Control display of actions based on context e.g. • Type, Aspect, Property, Site, Mimetype etc • Can use OOTB evaluators or define your own • Chain them together, all need to evaluate to true • See slingshot-documentlibrary-context.xml for OOTB evaluators
- 14. Action Types • Three main action types: o “link” – external link or link to content o “pagelink” – to another Share page (e.g. details) o “javascript” – client-side action • onActionSimpleRepoAction e.g. Simple Workflow approve/reject • onActionFormDialog e.g. Transform (to image), Run Action
- 15. Example: Mimetype Evaluator • Only show Import for ACP/ZIP files o share-config-custom.xml o custom-slingshot-context.xml
