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

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/"
}

Microdata
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)
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>
