Study Notes
Character Recognition Technology
- Applications detect character patterns in images, achieving accuracy up to 99%, influenced by document quality and user/software capability.
- Barcoding technology appears in 1-D and 2-D formats, known for high accuracy and limited data capacity, particularly for 1-D barcodes.
- Recognition technology is also available for audio, video, and other rich media types, often expensive and specific to certain applications and file formats.
Inherited Metadata
- Inheritance principle applies metadata to information objects, maintaining related documents in a classification scheme upon capture.
- Captured items receive mandatory metadata elements and optional entries based on their history before becoming official records.
- Declaration of records assigns additional metadata, including the declarer’s identity and timestamp.
- Security settings, retention periods, and disposal instructions are commonly inherited metadata from classes and files within the scheme.
Metadata from User Logins
- Metadata can be automatically captured from user profiles using protocols like Lightweight Directory Access Protocol (LDAP).
- Applications can input user details (name, job title, department) into documents created by the user without manual entry.
Metadata from Other Data Sources
- Existing databases can provide metadata through various mechanisms, aimed at reducing redundancy and improving efficiency by reusing stored data.
- The process can be manual or automated, with greater benefits from automation.
Metadata through Workflow
- Workflows streamline document-centric business processes and can also update related metadata.
- For example, status updating during a publication review can reflect stages like “In Draft” or “Approved”.
Enterprise Metadata Interoperability
- Path to metadata interoperability involves content silos (information management systems, shared drives) with varying field names and structures for common elements like publication dates and authors.
- Leveraging standards like Dublin Core aids in structural interoperability among silos, standardizing field names while retaining some inconsistencies in semantic values.
- Ideal interoperability results in consistent naming and semantic values across all systems, requiring collaboration among IT, information architecture, and end users for successful implementation.
