What are moby webservices?

• Technologically they are standard webservices

• Define a new layer on the protocol stack to:• Have a well known data

representation based on ontology

• Make easier the desired service discovery

• Make easier the construction of complex biological workflows (with support for error & async handling)

TCP / IP

HTTP

SOAP

Moby

Most common protocol stack in Moby

WSDL

Service Publication

MobyCentral

• Moby project provides Moby Central as a Perl server

• It is a directory of services, datatypes and how to locate them

• There are different kind of clients

• Some of them allow the creation of workflows

• Internet based client• Discovery of services based on data type

ontology or on service type ontology• It allows to connect easily service outputs to

service inputs• Interface helps to the Moby object

Data types and service ontologies

Client Side: Mowserv III

1) Ontology browsing & service selection

2) Input submission

3) Selection output name

4) Service submission

5) Check execution status

6) Check results

Client Side: Taverna I

• Java based graphical integrated workbench

• It allows the construction of complex distributed workflows

• It can handle different kind of services (Moby and others)

• Moby provides libraries for easier service development in different platforms & languages (Perl & Java)

• These libraries provide an abstraction of the underlayer protocols. The developer does not need to handle internet connections or SOAP messages and he can concentrate on the biological problem

Page 16: Moby Web Services

Server Side: jMoby

• For java development• Hides totally underlayer protocols• Automatic generation of code

(developer just needs to concentrate on the biological problem)

• Include graphical tools for develop, testing, deploy and execution

• Dashboard is part of jMoby
