5 Customized Metadata Tools Why make customized tools? Make important metadata elements more quickly accessible More closely link metadata edits with spatial/attribute edits Provide hints/assistance to ensure accuracy and completeness, adherence to Air Force standards Make metadata creation and maintenance easier and faster Automate batch changes Increased quality control!!! 5

6 Synchronizers The process by which properties of a data set are read from the data set and written to its metadata Purpose is to: Complete as much of the metadata as possible automatically Make sure metadata is kept up-to-date with changes to the dataset ArcCatalog comes with three synchronizers: FGDC ISO Geography Network (ESRI) 6

7 Synchronizers Synchronizers are fired when: A data set is selected in ArcCatalog and the Metadata tab is selected If there is no metadata, it is created and populated If there is metadata, it is updated When a user clicks the Create/Update metadata button in ArcCatalog Synchronizers can be disabled under Tools Options 7

8 Synchronization Process 1. Synchronization triggered 2. Update method called on synchronization manager, passes property of selected data set Synchronization manager 3. Synchronization manager finds all registered and enabled metadata synchronizers Component category manager ArcCatalog Metadata (XML) 5. Each metadata synchronizer writes to the data set s metadata 4. Synchronization manager passes the data set property to the Update method of each synchronizer identified Metadata synchronization 1 Metadata synchronization 2 Metadata synchronization 3 Source: Creating a Customized Metadata Synchronizer, an ESRI White Paper, July

9 Synchronizers Benefits An organizations name can be written each time metadata is created Contact information can be automatically written into the metadata Organizational specific hints can be automatically written into the metadata Organizational specific values can be automatically written to the metadata Undesirable effects (ie. writing of codified datum names) of default synchronizers can be eliminated 9

10 Synchronizers Air Force metadata valid values for specific SDSFIE Feature Classes can be automatically entered when the Feature Class is created 10

11 Editors The process by which metadata is manually created or edited Purpose is to: Provide access to metadata values to be entered or edited ArcCatalog comes with two Editors (ActiveX controls): FGDC ISO 11

12 Editors Editors are accessible when: A data set is selected in ArcCatalog, the Metadata tab is selected, and the open Metadata Editor is clicked The metadata editor that is used is selected under Tools Options, Metadata tab (default is FGDC). 12

13 Editors Benefits Editor form can be tailored to an organizations unique needs Organizational specific hints and directions can be part of the form (REQUIRED ) Can be made available in ArcMap Organizational specific values can be automatically written to the metadata 13

14 Editors 14

15 Style Sheets Customize the way that an organization sees the metadata Make metadata available for viewing in other applications Make metadata more readily accessible and user friendly by non-experts 15
