Informatics is the science of information, the practice of information processing, and the engineering of information systems. Informatics studies the structure, algorithms, behavior, and interactions of natural and artificial systems that store, process, access and communicate information.

What has been lacking, until recently, is a successful method to develop, implement and sustain informatics solutions to modern application problems, such as environmental and climate assessments, that provide interoperability among very diverse and heterogeneous data and information sources, as

We have used semantic technologies to design, implement, and deploy an interdisciplinary virtual observatory. The Virtual Solar-Terrestrial Observatory is a production data framework providing access to observational datasets.

We present a research effort into the application of semantic web methods and technologies to address the challenging problem of integrating heterogeneous volcanic and atmospheric data in support of assessing the atmospheric effects of a volcanic eruption.

We have developed a semantic data framework that supports interdisciplinary virtual observatory projects across the fields of solar physics, space physics and solar-terrestrial physics.

Semantic interoperability of mineral exploration geodata is a long-term concern in mining projects. Inconsistent conceptual schemas and heterogeneous professional terms among various geodata sources in a mining project often hinder their efficient use and/or reuse.

The Virtual Solar-Terrestrial Observatory (VSTO) Portal at provides a set of guided workflows to implement use cases designed for the VSTO Project.

The World Wide Web is a vast, diverse, and dynamic ecosys- tem of content authored and consumed with innumerable frequency. Al- though content may have an original purpose, it can and will be repur- posed in new and unexpected ways.

The field of translational biomedical informatics seeks to integrate knowledge from basic science, directed research into diseases, and clinical insights into a form that can be used to discover effective treatments of diseases.
