Orchestrating the ServicesThe HELIO services can be used individually or orchestrated together; this can be done in a number of ways:
Through the HELIO Front-EndThe HELIO Front End (HFE) is a graphical user interface that allows the user to define search criteria, refine the selection and then look for the data; behind the scenes the HELIO services are being used to answer a number of questions.
See the Screencast Tutorial describing how to use the HFE.
Using Taverna WorkflowsThe services can also be combined together using workflow tools; HELIO selected the Taverna Workflow Management System for the project. The HELIO workflow capabilities are discussed in the pages on the Capabilities pages.
A Taverna Workshop was held for HELIO Users at the University of Manchester during the third year of the HELIO project (February 2012). The following handouts were provided:
- An Introduction to Designing, Executing and Sharing Workflows with Taverna
- Taverna, myExperiment and HELIO Services
Access through Application SoftwareHELIO can also be accessed through different types of application software:
Using IDL/SolarSoft: The SolarSoftWare (SolarSoft or SSW) system has been developed by the solar physics community; it is based on the Interactive Data Language (IDL). SolarSoft has branches for many solar observatories and instruments together with a branch containing generic software.
Using Python/SunPy: The SunPy project is an effort to create an open-source software library for solar physics using the Python programming language. Software to access HELIO using SunPy is currently being developed.
Information on the Python/SunPy access will be provided when it becomes available.
