Best PracticesBest Practices
Implementation practices — “on the ground” rules of thumb and procedures
Because not everything should be codified in application rules — room should be allowed for experimentation
In these “gray areas” best practices can suggest non-prescriptive and reasonable sets of procedures

CrosswalksCrosswalks
Librarians Should be able to walk, talk, eat, and drink metadata of all varieties
Proficiency at this will require crosswalks, or algorithms for translating metadata from one schema to another
The same infrastructure could be used to merge multiple formats into a searchable index

Why It MattersWhy It Matters
We face many challenges and opportunities
Events have left our once robust metadata infrastructure behind — both conceptually and technically
Our users and the services we wish to provide them demand a metadata infrastructure equal to the tasks before us
We can and should seize the opportunity to recreate our foundational infrastructure
