Part of a monthly series of "tech talks" given for the University of Florida Libraries, BIBFRAME Working Group

1. Tech Talk

21 July 2015
Allison Jai O’Dell, Metadata Librarian | AJODELL@ufl.edu | (352) 273-2667 | 404 Library East

2. JSON

3. Why?
Data exchange format
Human-readable
Compact way to represent library data
Object-oriented = easier FRBRization

4. Examples
JSON:
{"employees":[
{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}
]}
XML:
<employees>
<employee>
<firstName>John</firstName> <lastName>Doe</lastName>
</employee>
<employee>
<firstName>Anna</firstName> <lastName>Smith</lastName>
</employee>
<employee>
<firstName>Peter</firstName> <lastName>Jones</lastName>
</employee>
</employees>

5. JSON-LD
Allows Linked Data to be serialized in a way similar to traditional JSON
Declare namespaces and URIs
{
"@context": {
"name": "http://xmlns.com/foaf/0.1/name",
"homepage": {
"@id": "http://xmlns.com/foaf/0.1/workplaceHomepage",
"@type": "@id"
},
"Person": "http://xmlns.com/foaf/0.1/Person"
},
"@id": "http://me.markus-lanthaler.com",
"@type": "Person",
"name": "Markus Lanthaler",
"homepage": "http://www.tugraz.at/"
}

6. Microdata

7. Why?
To add extra semantic meaning to HTML mark-up
To extend the HTML5 vocabulary
(so bots can understand, index, and use HTML documents –
read: Search Engine Optimization)

8. How?
Declare namespace for the element(s) you want to include
Add attributes to HTML elements
• itemscope
• itemtype=“namespace”
• itemprop=“name”
Example:
<section itemscope itemtype=“http://schema.org/CreativeWork”>
<p itemprop=“creator”>Allison Jai O’Dell</p>
</section>

9. Schema.org
Schema.org: “a collaborative, community activity with a mission to
create, maintain, and promote schemas for structured data on the
Internet, on web pages, in email messages, and beyond.”
CreativeWork, Book, Movie, MusicRecording, Person, Organization, Event,
Place, LocalBusiness, Product, Review + more
Bib Extend Community Group:“focused on establishing a consensus
within the bibliographic community around proposals to submit to the
WebSchemas Group for extending the Schema.org vocabulary”
