2. Metadata as Infrastructure

3. Example: Moving between two media types, both digital. Text Social datasets It is difficult to move between different kinds of document: e.g. Dataset of social statistics and passages of text. You cannot use text to search among numbers -- or numbers to search texts.

4. TextTOPIC LIST CaptionsSocial datasets Different media types on the same topic can be linked indirectly via topical metadata, but in this case you need to specify place also.

5. TextTOPIC LIST MapsGAZETTEERCaptionsSocial datasets Normalizing place names requires a gazetteer -- and latitude and longitude allow points on maps. But the time period is also needs to be specified...

6. TextTOPIC LIST MapsGAZETTEERCaptionsSocial datasets TIME PERIOD DIRECTORY Timeline Chronology So, normalize time terminology and calendar.
