0 Introduc.on 0 Research approach 0 Requirements for and elements of the open data e-‐
infrastructure 0 ENGAGE open data e-‐infrastructure
0 The ENGAGE development plan 0 Func.onali.es of the ENGAGE open data e-‐infrastructure
0 Conclusions
Introduc.on
0 Organiza.ons increasingly publish data on the internet à Open Data
0 Much poten.al to realize advantages
0 However, many organiza.ons simply release data without considering how these data can be reused (e.g. lack of contextual informa.on, linkage to other data, feedback tools)
0 While reuse of open data should enable the realiza.on of the advantages of open data
Introduc.on
0 E-‐infrastructure (based on ICT) can s.mulate and support data reuse (and provision)
0 Aim 1. derive requirements for an open data e-‐infrastructure; and 2. present such an e-‐infrastructure that meets a part of these
requirements à s.mula.ng realiza.on of open data advantages
Research Approach
0 Design Science Research Methodology1
0 Requirements for open data infrastructure gathered from: 0 Literature overview 0 Interviews 0 Ques.onnaire 0 Workshops

Requirements
0 Iden.fied 95 requirements in 12 categories: 1. Access 2. Searching 3. Naviga.on 4. Uploading 5. Downloading 6. Data quality 7. Analysis of datasets 8. Visualiza.on 9. Linking and combining data 10. Collabora.on 11. Support and help 12. Feedback
The ENGAGE development plan
Func.onali.es of ENGAGE open data e-‐infrastructure
0 No single e-‐infrastructure meets all requirements 0 ENGAGE 2.5 will not meet all of the requirements either 0 Most important func.onali.es of ENGAGE 2.5:
A. Data provision
B. Data retrieval and use
C. Data linking
D. User rating
E. User cooperation
Requirements (based on number in Table 1)
Key functionalities of the ENGAGE open data e-‐infrastructure
Data Acquisition, Metadata Acquisition, Data Cleansing, Data Validation, Data Conversion, Metadata Enhancement
21-‐23, 33, 44-‐47, 86, 92-‐93, 95
Retrieval by facets, Retrieval by query, Data display, Data requests module, Version management
Automated, Manual, Metadata
User profiles, Users as providers, Users as consumers, Users as co-‐operators
Rating system, Quality control
1-‐20, 27-‐28, 34-‐36, 39, 43-‐47, 64, 74-‐81, 88-‐95
14, 27, 29, 32-‐33, 49-‐60
29-‐33, 94
19-‐20, 61-‐72
Categories of functionalities of the ENGAGE open data e-‐infrastructure
Func.onali.es of ENGAGE open data e-‐infrastructure
0 Contribu.on of ENGAGE over exis.ng infrastructures: 1. Service for researchers and ci.zens 2. Metadata specifica.on and content organisa.on (embracement of
the Linked Data Paradigm while ensuring the quality and responsiveness of highly structured informa.on models)
3. Automa.on in data entry and cura.on 4. Crowdsourcing and interac.on with and between users of the
plagorm 5. Data cura.on tools and services 6. Dataset visualisa.on possibili.es 7. Mul.linguality 8. User help and training
Conclusions
0 Aim 1. derive requirements for an open data e-‐infrastructure; and 2. present such an e-‐infrastructure that meets a part of these
requirements à s.mula.ng realiza.on of open data advantages
0 Iden.fied 95 requirements of open data users and providers in 12 categories 0 Linked requirements to func.onali.es 0 ENGAGE 2.5 fulfils many requirements 0 ENGAGE is designed to interoperate within the general e-‐infrastructure
framework of the European Commission
0 Future research should show how the requirements for open data e-‐infrastructures could be further refined
