This document discusses the progression from sharing data on the web in documents to sharing linked open data on the semantic web. It begins by explaining how data in documents is difficult to access and use programmatically. It then outlines several steps to improve how data is shared, including making it machine-readable, using non-proprietary formats, adding semantic standards like RDF, linking data to other datasets, and generating websites to access the data. The goal is to share data in a way that is easy to access, use, and connect to other relevant data on the web.

Low TCO, high Impact: Innovative Government Services at Manatee Countybkraft
This presentation will discuss the Magnolia implementation for Manatee County Government.
Manatee County Government implemented both an intranet and Internet site using Magnolia EE with a small internal IT Team and a core group of 38 content editors. Manatee County leveraged the flexibility of the Magnolia STK to get an intranet site up and running quickly (4 Months). The intranet site provided content for the County's 1600 employees and served as a learning tool for developers, administrators and content editors while the Internet Site was under development.
Manatee County's new website now contains over 1,500 pages edited by 150 individuals from 17 County Departments. The site has multiple integration points with existing County information. Touch points include ESRI Mapping data, Oracle Enterprise data and Lotus Domino databases.
The discussion will focus on the Integration opportunities of County information into the STK.

US EPA Resource Conservation and Recovery Act published as Linked Open Data3 Round Stones

Briefing on US EPA Open Data Strategy using a Linked Data Approach3 Round Stones
An overview presented by Ms. Bernadette Hyland on 18-Nov 2014 on the US EPA Open Data strategy, focusing on the Resource Conservation & Recovery Act (RCRA) dataset to be published as linked data . This work is in support of Presidential Memorandum M13-13 - Open Data Policy and Managing Information as an Asset.
The W3C Data Shapes Working Group has been chartered in September 2014 to "Produce a language for defining structural constraints on RDF graphs and define graph topologies for interface specification, code development, and data verification." It will do for RDF what XML Schema did for XML.
This brief was presented as part of the RDF-AP Special Session at DCMI 2014, the Dublin Core Metadata Initiative Conference.
Open Data is the idea that "certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control”. Open Data follows similar “open” concepts that have proven to be valuable in the information economy such as Open Standards, Open Source Software, Open Content and has been followed more recently by variations on the theme such as Open Science and Open Government.
Open Data allows information of common value to be reused without needing to be recreated. The economic benefits of Open Data include cost reduction, organizational efficiencies and the facilitation of commonly held understanding. The costs of implementing Open Data deployment strategies tend to be iterative on top of existing information infrastructure.
This presentation will describe Open Data and its place in the ecosystem of economic and governmental discourse.

Improving Scientific Information Sharing by Fostering Reuse - Presentation at...3 Round Stones
Most scientific developments are recorded in published papers and communicated via presentations. Scientific findings are presented within organizations, at conferences, via Webinars and other fora. Yet after delivery to an audience, important information is often left to wither on hard drives, document management systems and even the Web. Accessing the underlying data for scientific findings has been the Achilles Heel of researchers due to closed and proprietary systems. This presentation shows an alternative to sharing scientific information using a Linked Data approach.

2. Towards Linked Open Data
●
On the Web with an open license ★
“It's great to have the data accessible on
the Web under an open license, however,
the data is locked-up in a document.
Other than writing a custom scraper, it's
hard to get the data out of the
document.”
3. Towards Linked Open Data
On the Web with an open license
●
★
Machine-readable data
★
●
“Splendid! The data is accessible on the
Web in a structured way (that is,
machine-readable), however, the data is
still locked-up in a document. To get the
data out of the document you depend on
proprietary software.”
4. Towards Linked Open Data
On the Web with an open license
●
★
Machine-readable data
★
●
Non-proprietary format
★
●
“Excellent! The data is not only available
via the Web but now everyone can use
the data easily. On the other hand, it's
still data on the Web and not data in the
Web.”
5. Towards Linked Open Data
●
On the Web with an open license ★
Machine-readable data
★
●
Non-proprietary format
★
●
●
RDF standards
“Wonderful! Now it's data in the Web. The★
(most important) data items have a URI and
can be shared on the Web. A native way to
represent the data is using RDF, however
other formats such as Atom can be
converted/mapped, if required.”
6. Towards Linked Open Data
On the Web with an open license
●
★
Machine-readable data
★
●
Non-proprietary format
★
●
●
RDF standards
●
Linked RDF
★
★
“Brilliant! Now it's data, in the Web linked to
other data. Both the consumer and the
publisher benefit from the network effect. ”
7. Path to Success

★
Don't include unstable identifiers
★
●
●
Automate publishing
12. Use a Non-proprietary Format
Standardized formats
