Pasquale Pagano manages service portfolios for projects like OpenAIRE and BlueBridge. He defines a service as a system that meets needs as defined by service level agreements and policies. Managing service portfolios presents challenges as the systems are designed for both human and machine access. The current portfolio includes many services powered by one technology. Services are registered and managed using the gCube system, which represents them as XML profiles adhering to schemas. Future plans include improving gCube and expanding support for projects like OpenAIRE.

4. How do you define/identify a “service” in your
domain?
A service is a system
supplying a need
governed by service level agreements
and regulated by policies
The D4Science catalogue allows services
• Discover
– ability to identify all and only the services according to the
consumer privileges
• Access
– ability to exploit the system’ capabilities in a secure context

5. What are the challenges in managing your service
portfolio?
Not tailored for human access
but designed to support also s2s communication
• Different views for different consumers
• Tailored views depending on privileges

Statistics form
openhub.net/p/gCube
• Each Resource (service, software, dataset, node, …) is represented with an XML profile compliant with
a predefined schema
• Resource schema are application profiles either inheriting properties from standards or defyning
custom properties
• Registration, validation, persistence, discovery, and access are served by a number of web services
(fully replicated and fault-tolerant)

9. What are your future plans in evolving service
portfolio management?
• New version of the gCube technology to
– Reduce the cost of operation
– Support medium-term evolution without porting
• Remove resource schema
• Allow runtime support for resource profile definition as
composition of basic facet types
• Support facet versioning
• Support not predefined resource relationships
• Projects
– (new) Edison, (extend the support of) OpenAIRE

10. Conclusions
• Not a single view of the service portfolio
– Tailored views for different consumers
• Not a single portfolio
– Tailored portfolio for different consumer privileges
• Not only service profiles
– Resource profiles and relationships
• Not fixed service schema
– Tailored service profiles for different domains
• Not only enabling discovery
– Enabling Access
