Open Standards in the Navy

Mar 5, 2008 Navy IT Day - Vice Adm. Mark Edwards, Deputy Chief of Naval Operations for Communications

• The Navy will acquire only systems based on open technologies and standards.

• “The days of proprietary technology must come to an end, we will no longer accept systems that couple hardware, software and data.”

• “Above all, we must break the stovepipes of data so that we can share information across domains.

• “We can’t accept the increasing costs of maintaining our present-day capabilities. In the civilian marketplace, it’s just the opposite. Some private-sector concerns are cutting their costs by 90 percent while expanding their performance.”

Benefits of Open Standards in DoD

• Increased security• Interoperability• Avoid vender lock-in• Supports best of breed

procurement• Encourages competition• Lowers cost

Open source

Standards create fertile ground for open source

C, C++ Gnu C, C++ compiler

POSIX GNU/Linux

HTTP Apache Web Server

SQL, ODBC MySQL, PostGreSQL

SMTP, POP Sendmail, etc.

.Net Mono

Standards Open Source Projects

Common Misconception #1

Open source projects are developed by hackers working in garages in the evenings and weekends

–Apache Foundation–Over 1000 committers–Only one is “volunteer”–Rest are employed by major corporations to

work full or part-time on Apache


Open source is the opposite of commercial software.

– There are different kinds of commercial software– Closed source

• Examples: Microsoft, Adobe, …

– Open source• Examples: Red Hat, MySQL, Zend, …

– Mixed: • Examples: Oracle, IBM, Sun, Novell, Autodesk,


People who require mission critical applications don’t use open source.

– Google – All servers run Linux– Oracle - Primary development platform is Linux– Over 70% of the world’s web servers – Run Apache– Deutsche Bank, Dresdener Bank – Run PHP– US Dept of Defence - Runs open source

Common Misconconception #4

Using open source means you have to release the source code for your application, and anything else that touches it.

–40+ different open source licenses–GPL – restrictive– LGPL - open–BSD – anything goes

Open Source Penetration

• Sector– R & D– Military– Municipal government– Telecommunications– Financial (Banks)– Utilities

– High– High– Significant and increasing– High (Mobile/Back-office)– Significant (Back Office)– Low, but increasing

Two models for developing software

Closed source–Microsoft Windows, AutoCAD, …

Open Source–Linux, Apache, MySQL, …

Open source is especially good where open standards have commoditized

Web Mapping and Commoditization

• Web mapping should be open source

– Widely-recognized standards OGC

– Less complex than desktop applications

– Web mapping is commoditized

– Successful open source community around MapServer

Benefits of Open Source in DoD

•Security

•Standards-compliant

•Flexibility and agility

•Quality

• Lower risk

•Reduced cost

Open Source and Security

Web 2.0 and Open Source Geospatial

• Open source is good at commodity software– Open standards create a fertile ground for commoditization

• http, html -> Apache Web Server

• Web mapping is being commoditized– Open source web mapping widely used– Successful businesses based on open source web mapping

• OSGEO provides a platform for Web 2.0 geospatialapplications.

Utility Web Applications

• Web-based application for managing engineering drawings

• Using FDO to integrating engineering drawings and geospatial data– Landbase– Parcel files

• FDO also used by 3rd parties - 1Spatial, Supermap, MapInfo, …

GeoREST web applications

Tim Berners-Lee, in Government Data Design Issues, proposes

•Geodata on the web in raw form.

•Raw geodata must be searchable

Open Govt Geospatial Data

www.GeoRest.org

GeoREST Relies on the Web

• URI

• HTTP (GET, PUT, POST, DELETE)

• HTML

• Mime: JSON, KML, PNG, …

• C-Templates

www.GeoRest.org

GeoREST provides FDO web services

• Exposes FDO as web services

• Provides 3rd party application access to FDO data

• Company required by government to report any problems with water

• Citizen can go to web site• Identify the city ward or suburb in which he/she

lives• Find notifications of problems

City of Nanaimo Geodata

Business Problem

• Reporting – simple, no programming access to geodata in NanaimoMap

• Support Google Search - Provide users to search for public geodata without having to learn a new query system

• Open data access - Provide geospatial data in a variety of "Neo-Geography" formats like KML, GeoJSON, …


Solution

• GeoREST web services architecture

• Access to data configured via XML and Google CTemplate to deliver multiple representations (KML, GeoJSON, …) of the same features with no programming.

Development• SL-King and City of Nanaimo
