US Environmental Protection Agency - Feb 26, 2016

Today’s reality at EPA

»Tens of thousands of sources

»Many formats - JSON, XML, CSV, PDF, PPT, SHP, SHX, text, binary…

»Thousands of data silos

»No single source of truth

»Varied interpretations

»Brittle interfaces - lack of interoperability

Potential at EPA …

• Findable data

• Accessible data

• Interoperable data

• Re-usable data

• Shared context

• Data Platforms (HDFS, NoSQL)

Linked Data is helping to extend & augmentEPA’s significant investment in enterprise relational technologies

How?

By leveraging NoSQL Data Platforms that rigorously adhere to international data interoperability standards. *

* Relevant international data exchange standards are published by the W3C, OGC, IEEE

Graph databases, as a subset of NoSQL databases, are the most efficient way to look at the relationships between data

items, patterns of relationships and interactions.Image Credit: Cray, see http://www.cray.com/blog/graph-databases-101/

Graph Databases 101

Hadoop Integration»While over 90% of the world’s data has been created in the last two

years, EPA has tremendous variety of data requires the “right tool for the job”

»Historic data (“short, wide, complex data”) vs.

»Granular sensor & GIS data (“long skinny data”)

»Core mission-based systems with robust historic data, includes:

»Toxics Release Inventory (TRI)

»Facilities Registry (FRS)

»RCRA Handler

»EPA’s enterprise information architecture should include a data platform that leverages Hadoop: HDFS and MapReduce, and accommodates EPA’s robust data landscape.

»Must support modern, open source tools for application development, visualizations, crowdsourcing, and deployment on the Web

One option - MarkLogic Integrates Hadoop Ecosystem &EPA’s Robust Data Landscape

EPA Robust Data Ecosystem is adaptable using a Linked Data Approach

» Makes data integration faster and easier » By using a global addressing scheme, HTTP URIs.

» Uses semantics to “glue” together data faster.» Common semantic definitions link traditional relational

models.» No more out of data documentation using standard

vocabularies.

» Robust search and discovery by leveraging the semantic graph.

» Scales to the Web!

9

All modern data platforms deployed at EPA should

»Support options for data modeling - Linked Data (JSON-LD, RDF), SQL (JSON, XML)

»Native store and query of documents, blobs and structured data.

»Standards-based query interface across documents and data, e.g., Full support for SPARQL 1.1

»Offer enterprise functionality including high availability & disaster recovery, scalability & elasticity, ACID transactions

»Be deployable on FedRamp certified cloud provider certifying controls for security, high availability, disaster recovery

»Scale to billions of statements, triples, etc.

»Store unstructured data across clusters like Hadoop, making it easy to move data partitions.

»Much but not all of EPA’s data is well suited for a Linked Data approach.

»Linked Data is based on 20+ year old idea, a system of linked information systems

shared innovation™

Search for facilities where we live. Unlike many EPA Web portals, linked data is human AND machine readable data. No screen scraping is required. Encourages re-use (discourages data silos)

The EPA Linked Data service CONNECTS data silos, and provides familiar map and table data views

Click to drill down to pollution reports that combine data from 5 previously unconnected data silos.

Click through to the source of the pollution data via the source reports (TRI).

EPA collects granular pollution data. Linked Data opens up the data to a much wider audience in a human readable format.

Previously, only people who employed complex screen scraping techniques could get at this data. Now, EPA open data is available using an international data standard, with one click!

Good news story!Pollution graphs created in one week using Open Source Software & EPA Linked Data

Use of shared vocabularies, e.g. Places, Geographis, Dublin Core, Geo, FOAF, ORG, Vcard are the “lingua franca” of data interoperability
