Marklogic and the Linked Data Connection

MarkLogic and the Linked Data Connection

Philip Fennell, Consultant22nd May 2012

Big Data is big news

Volume, Velocity and Variety are growing…

...but the Value is in the Connections

Big Data’s Valueis underpinned by Linked Data

Linked Data is built uponSemantic Web Technologies

RDF and SPARQL

A lack of standard protocols...

...led to implementation specific APIs

and additional complexity

New protocols from the W3C

SPARQL 1.1 Graph Store HTTP Protocol

SPARQL 1.1 Protocol

SPARQL 1.1 Graph Store HTTP Protocol

Graph Dataset Management over HTTP

SPARQL 1.1 Protocol

SPARQL Queries over HTTP

Support is Growing for these protocols

GRASP GRaph store And SPARQL Protocol

A GitHub project

https://github.com/philipfennell/grasp

XQuery client libraries

lib-gsp.xqy - Graph Store HTTP Protocol

lib-spq.xqy - SPARQL Protocol

A wide range of functionsgsp:add-default-graph, gsp:add-named-graph,

gsp:retrieve-default-graph-metainfo, gsp:retrieve-named-graph-metainfo,

gsp:retrieve-default-graph, gsp:retrieve-named-graph, gsp:merge-default-graph, gsp:merge-named-graph,

gsp:delete-default-graph, gsp:delete-named-graph, gsp:data,

spq:query, spq:data

But why so many functions?

I don’t like too many arguments!

I don’t like optional arguments!xdmp:document-insert(

'/books/collection/A123.xml',<book> <title>Linked Data</title></book>,(), (), (),5780546120451828821

A RESTful interface for Graph Stores

Linked Open Data has expandedto this in just five years

The defining factor in the Realization of Big Data's Potential

Time for a Demonstration
