Proposal 1: Native inbound and connector for IBM MQ 7.5
Description
Currently with WSO2 Enterprise Service Bus recommended way to connect to IBM MQ is using JMS transport. But this has limitations and sometimes gives issues when integrating.
...
Microservice Framework for Java (MSF4J) [1] is a lightweight, fast runtime that can host annotation based services, such as JAX-RS in a micro service architecture[2]. Microservices developed using WSO2 MSF4j can start in just a few milliseconds in a Docker container and can easily be added to a Docker image definition.
MSF4J requires development tooling to make it appealing to the Java Development Community. It requires end-to-end tooling that helps developer to implement a microservice, run and unit-test a microservice in the integrated development environment itself.
Deliverables
IntelliJ IDEA Plugin for running a Java Service in MSF4J
Eclipse Plugin for running a Java Service in MSF4J
...
Java
Eclipse plugin development
IntelliJ plugin development

In Machine Learning, Ensemble learning is a combining of multiple learning algorithms/models to obtain better predictive accuracy than what could be obtained from a single learning algorithm. Final prediction is done by taking a weighted vote of the predictions of the combined algorithms. Currently WSO2 machine learner does not facilitate this. The main tasks of the project is to:

Proposal 13: [ESB/Tooling] Automated tests for ESB Graphical editor using SWTBot
Description
Currently we do not have automated tests for ESB graphical editor[1] which is a GMF based drag and drop tool to develop ESB configurations. We can use Eclipse SWTBot[2] to implement automated tests for these kind of GMF editors. Idea is to implement an automated test suite to cover graphical functionalities of ESB editor by composing mediation flows which involves Proxy services, APIs, Sequences, Endpoints, mediators and their properties etc.
...
Proposal 14: [ESB/Tooling] Support JSON, CSV, Java, Excel and Web services formats in Data Mapper tool.
Description
Today, enterprise applications use different data formats and different data structures. WSO2 Data Mapper tool can be used to map different data formats/structures between two systems/applications while system integrations. WSO2 Data mapper tool is based on Eclipse GMF and builds graphical input data model and output data model using provided Apache Avro[1] schemas.
Developers can extend Data mapper tool to support any data format by adding a data type transformer to generate Avro schema based on the relevant data format(Eg: JSON, CSV etc). This project is to write data format transformers to transform CSV, JSON, Java, Excel, Web services formats to Avro format.
Deliverables
Components for generating Apache Avro schemas for data formats such as JSON, Java, Excel, Web services.

Proposal 21: [IS] Document Based NoSQL Support for WSO2 Identity Server Database
Description
WSO2 Identity Server out of the box supports LDAP, Microsoft Active Directory and Relational Databases as User Stores. With the fast growth of enterprise level NoSQL databases, it is important to support NoSQL [1] user stores to improve the value that WSO2 Identity Server can deliver to enterprises in terms of user data management.
In order to support NoSQL, It is expected to customize or write a new User Store Manager [2] that supports storing/retrieving data from NoSQL databases.
The database architecture has to be completely redesigned for optimizing the performance of operations. Initially, new document collections can be created for each database table referring the current relational database schema. Some of the document collections can be combined together as embedded documents or new data models [3] should be created for performance improvement considering the following facts.
- Document size considerations
- Complexity of data structures
- Data Consistency
The performance has to be further improved by creating appropriate indexes.
Initially the project should be done on MongoDB 3.2 [4] which is a Document based NoSQL database that is widely used [5]. Test automation should be done appropriately as Unit Tests or Integration Tests for all the operations in the userstore manager.
Based on completion, other Document based databases such as CouchDB, RavenDB can be considered for implementation.
Deliverables
- Database Architecture Diagrams
- Custom Userstore Manager
- Automated Tests
- Developer documentation
- Articles/blog posts on using the custom userstore manager
Skills Needed
- Java
- Database knowledge and SQL
- Understanding of NoSQL
- MongoDB 3.2
- Using MongoDB with Java [6]
- Test Automation (Junit, Selenium)

Proposal 29: [Cloud] Native Cloud Support for Running WSO2 Middleware on Microsoft Azure
Description
WSO2 middleware can be deployed on Microsoft Azure either using virtual machines or containers. In this project will focus on Virtual Machine approach as container support is still primitive on Azure (except for running Kubernetes on Azure). To do this we need implement a Carbon Membership Scheme for providing automatic cluster discovery similar to Kubernetes Membership Scheme [1].
In addition, we need to demonstrate how following areas would work on Microsoft Azure with native Azure features:
- Auto healing
- Autoscaling
- Automatic cluster discovery
- Dynamic load balancing
- VM/Container support
- Multi-tenancy
- Configuration orchestration
- Artifact distribution
- Software update distribution
- Multi-region/cloud deployments
- Centralized logging
- Monitoring

Proposal 31: [ML] Deployable artefact model for WSO2 Machine Learner
Description
WSO2 Machine Learner provides a user-friendly wizard type interface where you could configure machine learning analyses and generate models. However, we do not have a concept of deployment artefacts, where you could deploy a dataset, project, analysis simply by dropping a file artefact into respective deployment directories.
The main tasks of the project is to:
- Define the architecture
- Define artefact definitions
- Implement deployers
- Refactor ML back-end
After introducing this model;
- We should be able to deploy ML artefacts via a Carbon Application (CApp) - increase the portability
- We should be able to build an automated model creation system. i.e. we configure an analysis to run periodically that would pick the latest dataset version and build a new model and deploy it if it's more accurate.
- We should be able to hot deploy artefacts
Deliverables
- Deployable artefact model for WSO2 Machine Learner.
- Artefact definition file/s
- Tests and documentation
Skills Needed
- Basic Machine Learning knowledge
- Java
