Today’s Web
• Suitable for human consumption
• Markup consists of: – rendering information
(e.g., font size and colour)
– Hyper-links to related content
• Semantic content is accessible to humans, but not (easily) to computers…

o e-Paper formats (easily human readable)• Text data• PDF• HTML
o Raw data (human readable and computer can read)• XML data• Excel files• CSV
o Semantic WEB (easily readable by computers)• RDF• OWL• microformat

o Open data is the data on the site is available to the public, but it doesn't link to other data sources on the Web. • It could be data that has been uploaded in CSV format (i.e. spreadsheet
data)
o Linked Data is a 'web of data.'• The idea of Open Data is to turn it into Linked Data• The first priority is to publish lots of Open Data. • The next step is to work towards linking it all up. • Data.gov.uk is currently a combination of Open Data and Linked Data

o No information systems in place• Data is in Word documents
o There is an information system but no data is published
o Well developed information system with large amount of published data

FINKI Open Data
o The Faculty of Computer Science and Engineering joins the trend by making parts of its data available as open data.
o Information about all the faculties in our university such as names, addresses, phones, email and web pages.
o We publish more information about our Faculty - Institutes, Modules, Programs, Courses, Subjects and Employees.
o Implemented using available tools

o Create Open Data Portal (data.gov.mk)• Develop clear security guidelines• Move the existing data sets to data.gov.mk
o Create and publish data sets useful for larger population and crate mobile and web applications
o Start publishing row datao Build new systems with automatic data publishing
option

o We need to change our minds • To provide a means of computers to help us
o The technology is here• We lack data. • Additional effort is needed to publish data in computer readable
format
o There is good foundation for open data in Macedonia• @FINKI have research group deeply involved in Semantic Web
and Open Data• Many institutions already have high quality data in digital format
o We should strive to Web 3.0 (Semantic web)• web of data
