The VIVO architectural fly-in will be focused on bringing an architecturally-minded team together who individually represent distinct VIVO stakeholder constituencies for the purpose of developing architectural approaches required to address the direction of the project. The primary goal of the two-day face-to-face meeting will be to assess and document a plan for improving the VIVO application architecture towards enabling and realizing the technical efforts defined in the "Statement on VIVO's Product Direction for 2019".

The success of this effort relies on balancing the perspectives of:

  • Research Intelligence
  • Modern web interface
  • Semantics and ontology
  • Modern development tools and practices
  • Performance / Scalability, and
  • Existing VIVO architecture

Who

Agenda

2019-01-29 to 30 - VIVO Arch Fly-in f2f Meeting

Requirements

  1. VIVO must support ingest rates of x-number of triples per hour

  2. VIVO must support total scale of y-number of triples
  3. VIVO must support the removal of triples, regardless of the number of triples or size of graph
  4. VIVO must support response times of < 2sec for profiles, regardless of number of relationships
  5. VIVO must service any frontend user interface via an API
  6. VIVO must support API-driven integration tests
  7. VIVO must support the swappability of the following components
    1. Search index
    2. Triplestore
    3. Asset store
  8. VIVO must support ingest without stopping other components (indexer)
  9. VIVO must support configuration update without requiring application restart

Considerations

  1. VIVO should be designed towards being "cloud-ready"

Thoughts / Notes / Resources

Components to decouple

  • Core
  • Search index
    • Searching and indexing can be separate components
  • Triplestore(s)
    • Reasoners - ABox and TBox
  • UI
  • Authentication
  • Authorization

Interfaces for decoupled components

Core

  • What endpoints / services are required by UI?
  • Starting point: Classes with @WebServlet annotations

Search Index

Triplestore

Mixed Components

  • Not all components are easily compartmentalized, like APIs or TripleStores 

  • Consider Authentication, which includes:
    • back-end business logic, 
    • data model storage,
    • UI elements
  • If we wanted to support a new authentication scheme (say, two-factor authentication), we would need changes in all of these areas.

Component packaging

  • Back-end code can be delivered in a JAR file
  • How is front-end code delivered?
  • What about mixed components?

Community contributions

Scenario:

  • University X develops a new Triplestore component, called newTriple
  • University Y wants to use newTriple
  • One possibility is to wait for VIVO central to adopt newTriple into the core distribution. Then University Y can upgrade their system to the latest release, to get newTriple
  • What are other possibilities?
  • This leads back to packaging.
