zip file o Download RDF Refine Extension - a Google Refine extension for exporting RDF from: o http://refine.deri.ie/ o Extract the zip file to the folder /webapp/extensions
Step 3 – Create Project o Double
click on google-refine application o New tab will open in browser with google refine workspace o Click on Create Project o Click on Get Data From This Computer and choose excel file “resident_population_census2011.xls” o Click Next
CLEAN MESSY DATA
Step 4 – Unifying and Cleaning Data Click on the Worksheets you wish to Import: In this example is only one o To remove unwanted empty rows and cells o
o Uncheck Store blank rows o Uncheck Store blank cells as nulls
Type ignore first 1 line(s) at the beginning of file to remove unwanted rows o Parse next 1 line(s) as column headers to indicate the headers of our data columns o Click on Create Project o
Step 4 – Unifying and Cleaning Data
We can see that 20995 rows were imported to our project Click on Show 50 rows to view more data rows Still we need to remove some unwanted columns to get the raw data we need Remove columns: ◦ Επίπεδο Διοικητικής Διαίρεσης ◦ α/α ◦ Columns 6,7 and 8 By clicking on each column -> Edit column -> Remove this column
Step 4 – Unifying and Cleaning Data Also we wish to remove the first 4 rows which are totals from the data o We click on the of each row we wish to remove o Click All and then choose Facet – Facet by star to filter our dataset o On the left side you can now see two options: o
o True o False
Click on True -> All -> Edit Rows -> Remove all Matching rows o Click on False to see the remaining data. o Our Data are now Unified and Cleaned. o
BUILD RDF SKELETON
Step 5 – Reset RDF Skeleton o To
view and edit the RDF skeleton click on the RDF extension and then click on Edit RDF Skeleton… o You can see a basic skeleton generated automatically by the RDF extension. o However, is not a properly design structure so Click OK and then Click again on RDF extension but this time click on Reset RDF Skeleton… and OK
Step 6 – Add prefixes o Since
we wish to work with Data Cube Vocabulary we need to update the necessary prefixes
o Click on RDF -> Edit RDF Skeleton o Click on add prefix and type qb on the prefix field and click anywhere in the window o The URI field will be updated automatically o Click Save!!!
Step 7 – Base URI and URI patterns o Click edit and type http://linkedstatistics.gr o Before start building the skeleton it is important that you have already decided the URI patterns that you will give to your structure and data o The URIs we are going to use are the following: o Dataset http://linkedstatistics.gr/data/{table_name} o Schema – Structural components (DSD, Components Specifications)
http://linkedstatistics.gr/schema#{name} o Vocabulary (dimensions, measures, attributes)
http://linkedstatistics.gr/dic/{id} o Vocabulary Values
http://linkedstatistics.gr/dic/{id}#{value} o Observation Values
http://linkedstatistics.gr/data/{NameofDataset}#{Values of Dimensions sxeparated with comma}
Start Building Skeleton based on Data Cube Vocabulary
Step 8 – Define Components o Dimension(s)
ogeocode : Γεωγραφικός Κωδικός Καλλικράτη o Measure(s)
opopulation: Μόνιμος Πληθυσμός o Attribute(s)
oUnit of measure : Number of people
Step 8 – Define Components o
(8a) Define geocode o Click on add rdf:type and type qb:DimensionProperty o Click on (row index) URI o Choose The cell's content is used ... as a URI o Choose Constant Value and type the URI for this dimension (no need to repeat the base URI): dic/geocode
o Click on add:property -> property? -> rdfs:label o Click on Configure o Choose The cell's content is used ... as language-tagged text: el o Choose Constant Value and type: Γεωγραφικός Κωδικός Καλλικράτη

o Click on add rdf:type and type qb:DataStructureDefinition o Click on blank (cell) oChoose The cell's content is used ... as a URI oChoose Constant Value and type: schema/PopulationPerGeocodeCensus2011 oClick Save !!!
Step 9 – Define DataSet, DSD and Components Specifications o
9c) Define Component Specifications with dimensions, measures and attributes o Click on add:property -> property? -> qb:component (Repeat 3 times) o Click on Configure on each three new components o Choose The cell's content is used ... as a blank node to create a new node for the Component Specification node and click OK o Click on add rdf:type and type: qb:ComponentSpecification o Click on blank (cell)
