| Software and workflow approaches | ||
| Proprietary, homegrown, open source, partnerships | ||
| Centralized versus desktop | ||
| Requirements | ||
| Metadata flexibility | ||
| Avoid vendor lock-in – exportable data | ||
| Distributed management with approval queue | ||
| Open standards | ||
| Support and continued R & D | ||
Example: detailed software criteria
| Allows collaborative and distributed collection development/management | |
| Platform (hardware, operating system) agnostic – server and client | |
| Web-based client with easy-to-use interface | |
| Basic and advanced searching across collections, across sites (federated searches, virtual collections, stored result sets) | |
| Common client-side players/viewers | |
| Client tools for manipulation, comparison, per-user annotation | |
| Flexible support for metadata standards | |
| Support for many object formats, and developing formats (e.g., jpeg 2000) | |
| Support for high-resolution, zoom-in features | |
| Supports Unicode text for display and searching | |
| URL access to objects | |
| Customizable display interface | |
| Based on open standards (database, metadata, etc.) | |
| Flexible access control list features | |
| Standards-based export functions to avoid “lock-in” and promote remote indexing |

CONTENTdm
web-based administration
| Thumbnail, service and full resolution images stored in directories in standard image formats |
| Metadata exporting |
CONTENTdm metadata flexibility
| Metadata is expensive | ||
| Time required for content specialists to create and proof key fields of metadata | ||
| Balancing metadata quality with results | ||
| Risks of not finding materials | ||
| Risks of “dirty” results | ||
| Perfect can be the enemy of good | ||
Indexing binary content (images)?
| Distributed and supported by OCLC | ||
| Predictable costs | ||
| Continued development | ||
| JPEG2000 | ||
| PowerPoint plug-in | ||
| Community open source developments | ||
| Proprietary software + open standards has led to an open source community | ||
| Controlled vocabulary analyzer | ||
| Importable Library of Congress Subject Headings | ||
| E-commerce extension for ordering images | ||
| RSS feed generator to subscribe to collections | ||
| Direct linking to objects | ||
| XML Gateway for federated searching of CONTENTdm collections | ||
| Feedback tool for commenting/reviewing objects | ||
| OASIS – a web-based tool for organizing and importing images | ||
| On a “per image” basis | ||
| Insectary: | ||
| links to blogs for each image | ||
| REALIA: | ||
| feedback data sent via email to collection administrators | ||
