With everything else happening in the world, why does

Open Data matter anyway??

Discovery, access & re-use goes beyond government transparency &

accountability … !

Access to timely, accurate data is vital to

first responders, legislators, scientists, policy makers,

journalists & the general public

Taxpayers spend billions of dollars for our government to

collect data

We, the people, expect government authorities to treat information

as an asset. It complies with regulations (Quality

of Information Act, Section 508, protects PII) & is:

public, accessible, described, reusable, complete, timely, sustainable over

election cycles

US Federal Government is listening … “Open Data” per M13-13*

• Public

• Accessible

• Described

• Reusable

• Complete

• Timely

• Managed Post-Release

• Project Open Data

• OMB & OSTP online tools, best practices & schema to help agencies implement M13-13. See Project Open Data

• May 9, 2014 the Digital Accountability & Transparency Act (DATA Act) became Public Law 113-101

The goal of treating Information as an asset is

not new …

“Linked Data was part of my initial vision for the Web and is an important part of the Web’s

future. The Web took off as a web of hyperlinked documents which were exciting to read, but which could not be effectively used as

data.

“Linked Data was part of my initial vision for the Web and is an important part of the Web’s future. The Web

effectively used as data.” !

- Tim Berners-Lee

We all know the ground truth of data on the Web

Lots of [government] open data without labels or context

What is needed is … data that describes itself

Linked Open Data is called “self-describing” data

Linked Data is “A method of publishing structured data so that it can be interlinked &

become more useful. … Extends Web pages to share information in a way that can be

read automatically by computers.”

• Linked Data has one amazing property: it can easily be combined with other Linked Data to form new knowledge.

• Based on 20+ year old idea

• A system of linked information systems

FOREWORD BY Tim Berners-Lee

Structured data on the Web

We’re making progress with US Government

Open Data

• On our third iteration of a catalog of datasets, using CKAN. • >500k datasets from 200+ USG authorities

• Sustained executive support for data.gov via OMB & OSTP - Project Open Data • GSA team who are engaging with Open Data / OSS /

standards community • Health, Energy, Law, Education & Public Safety specific

communities in place. • Agencies are [beginning] to name Chief Data Officers !

But we still have a lot to do …

RCRA = Resource

Conservation and Recovery

Act

A search for “EPA RCRA” shows displayed

the first dataset 6th position :-(

This dataset is just one piece of a complex set

of data in understanding solid

waste reporting

First 5 results are for

Facilities Registry

Service …

For example, The Right-to-Know Network is a

consumer of EPA open data from

data.gov

They’ve build some nice

visualizations!

But the Toxics Release Inventory (TRI) is

complicated data . The RTF Network

would have benefited from more context

had it been available from the EPA…

RTK Network provides access

to machine readable content (as XML) but … it lacks context

This data does not use shared vocabularies!

:-( No units of

measure, No definition of codes

List of input reports for this pollution report … Possible because of a linked data approach

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

Summary

• Billions of dollars are spent by taxpayers for government to collect useful information - e.g., geospatial data, population, healthcare, medicine & clinical trials, environment, energy, law, education …

• Data consumers must help government to fulfill its goal to treat “information as an asset” by participating & giving feedback

• Steady forward progress has been made however, take care to not re-create the wheel!

• Use Open Data, Open Source, Web standards & published best practices whenever possible

• More work to be done …

– Open  Data  is  the  idea  that  "certain  data  should  be  freely  available  to  everyone  to  use  and  republish  as  they  wish,  without  restric%ons  from  copyright,  patents  or  other  mechanisms  of  control”.  Open  Data  follows  similar  “open”  concepts  that  have  proven  to  be  valuable  in  the  informa%on  economy  such  as  Open  Standards,  Open  Source  SoRware,  Open  Content  and  has  been  followed  more  recently  by  varia%ons  on  the  theme  such  as  Open  Science  and  Open  Government.
