Introduction - IATI

“IATI is a voluntary, multi-stakeholder initiative that seeks to improve the transparency of aid in order to increase its effectiveness in tackling poverty.”

Introduction - IATI users

• Funders o Where is the money of my organisation spent?o Where do other organisations spend their money?

• Governmentso How much money is spent in my country?o What are the budgets or planned disbursements for my country?

• Localso What organisations are working in my area?o What projects are currently going on in my area?

• Publico Where is my tax money going?o What are the organisations doing with my donations?

Introduction - Linked Data

1. HTTP URIs to name things

2. Create meaningful links to other datasets

3. No more data silos

4. Standardized vocabularies and ontologies

5. Query datasets through SPARQL

Introduction - Why IATI Linked Data?

1. Reusable vocabularieso Extract information automatically from the IATI data by

making use of applications which are able to interpret standard vocabularies

2. Enrich IATI datao Link IATI data to external datasets in order to enrich the

IATI data with additional information or metadata.

3. Donors can use their own Linked Data specification.o @Linked-data-uri attribute already exists in the IATI

model.

Linked Data model

1. How can the IATI model best be converted to a Linked Data model?a. How can we create the Linked Data model in a

structured manner?b. How can we keep track of provenance on the

IATI data?c. What standard vocabularies can be reused for

enriching the Linked Data model?

Linked Data model - Provenance

• On file levelo Not on activity level

• A named graph per file, e.g.:iati:graph/dataset/Worldbank

Linked Data model - Triple store

• Triples loaded into a ClioPatria triple store:o http://eculture.cs.vu.nl:1987/iati/homeo Sparql endpointo Dereferenceable URIs

(http://purl.org/collections/iati/codelist/Sector/11420)

• Total number of triples: 36,629,017

• Total number of named graphs: 4,790o Largest activities graph is UNOPS containing

1,231,896 triples

• Takes approximately 30 minutes to load all data into the triple store.

Linking datasets - Approach1. In total, how much does a given country receive in aid?

2. A comparative index of aid versus the Human Development Index.

3. What is the geographic location of a project? How much aid went to a given province, constituency or village?o Is the aid spent in places where the need is highest? Is it well

distributed across the country?o Can we attribute sub-national breakdowns for aid so we can see how

much goes to different parts of recipient countries?

4. How does violent conflict in recipient countries affect aid activities?

5. How does aid spending as registered in the IATI standard compare to World Bank indicators?
