What do users need?(the question that answers all the other questions)
![Page 3: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/3.jpg)
Schaffner’s synthesis of user studies• Users search by subjects and keywords• Users expect results ranked by relevance• Users expect comprehensive coverage• Users know how to scan and scroll• Users lack awareness about collections
Schaffner, The Metadata is the Interface. http://www.oclc.org/programs/publications/reports/2009-06.pdf

Users search by subjects & keywordsLet’s buff up subject and keyword access!
![Page 5: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/5.jpg)
Better Indexing• Appropriate hierarchies & subdivisions
match the granularity of user searches and browses
• User-supplied “tags”added value
show how users want to access and organize library resources;
data that libraries can use to inform better metadata and services
• Control (and publish!) local vocabularies• URIs

Things, not Strings
![Page 7: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/7.jpg)
Abstracting• Support keyword access• Provide context• Let users know:
What it featuresWhat it isWhat it can be used for
![Page 8: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/8.jpg)
Topic Modeling• Cluster related subjects together
ID collection strengths (“shop your closet”)
Let users surf related things
• Lets us get away with iffy dataDoes not require that every item in a subject area has the exact same heading
![Page 9: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/9.jpg)
Users expect results ranked by relevanceLet’s support appropriate results!
![Page 10: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/10.jpg)
Relevancy Ranking• Based on: where the search term appears
Subject headings TitleAbstracts Author-supplied keywordsFull text
• Based on: what it isCurrent publication Peer-reviewedType of material Length of material
… We can do better

Semantic SearchSemantic search technology relates user search queries to their probable intent, thereby offering more relevant results. This technology is built on a combination of understanding humans (e.g., natural language processing, concept matching) and understanding data (e.g., easily-parsed, uses URIs).

Users know how to scan and scrollLet’s support browsing!

Arrangement• Classification & call numbers• Shelflists• Series• Controlled access points
Subject & genre headingsCreators & other names

Uniform Resource Identifiers (URIs)Controlled access points … For the interwebs!
• Connect library collections
• Let users surf library resources alongside the Web

Users lack awareness about collectionsLet’s put collections in their face;Let’s get the metadata out there!

Put Your Metadata Other Places
![Page 23: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/23.jpg)
Let Folks Access Your Metadata• OAI-PMH & OAIster• APIs• SPARQL endpoints• Data dumps• Export options
• Linked Data: expose data to the Web• URIs: create links between library metadata & other resources
![Page 24: Designing Metadata to Meet User Needs for Special Collections](https://reader034.vdocuments.net/reader034/viewer/2022051213/55a5d10f1a28abc9298b489b/html5/thumbnails/24.jpg)
Create Shareable Metadata• Content is optimized for sharing• Metadata … reflects consistent practices• Metadata is coherent• Context is provided• The metadata provider communicates with aggregators • Metadata and sharing mechanisms conform to standards

More ConsiderationsInternationalization• Use clear, concise language
• Cultural relevance
• Character encoding
Policy• Explicit CC license
• Own the data you share
