A case study in adaptable and reusable infrastructure at the Keck Observatory Archive: VO interfaces, moving targets, and more
This paper describes how KOA is currently leveraging and extending open source software components to develop new services and to support delivery of a complete set of instrument metadata, which will enable more sophisticated and extensive queries than currently possible.
Making AEON a reality using APIs: experience integrating LCOGT and SOAR
An observation request language was developed suitable for describing observations across a wide range of current and future telescope facilities and observing resources, and an alternate option for observation management in the open source Observatory Control System (OCS) is introduced.
A citizen science exploration of the X-ray transient sky using the EXTraS science gateway
Creating an integrated collaborative environment for materials research
The infrastructure provides a web-based interface supporting group and project spaces within which researchers can easily organize, share, and collaborate on the results of their experimental and computational efforts.
Using the Agile Software Development Lifecycle to develop a standalone application for generating Colour Magnitude Diagrams
The CMD Plot Tool application functions “out of the box” without the need for the user to install code interpreters, additional libraries and modules, or to modify system paths; and it is available on multiple platforms.

BEANS software provides a clear interface for querying, filtering, aggregating, and plotting data from an arbitrary number of datasets to simplify the process of storing, examining and finding new relations in the so-called Big Data.
Architectures and methodologies for future deployment of multi-site Zettabyte-Exascale data handling platforms
The findings of a working group composed of experts from several scientific fields are described, estimating that by the 2020 decade they will require data handling systems with data volumes approaching the Zettabyte distributed amongst as many as 1018 individually addressable data objects.
Methodology to sustain common information spaces for research collaborations
A methodology to sustain CIS and a conceptual framework that has its foundations on a set of agreed Core Concepts forming a Canonical Core (CC) are introduced that leverages and promotes reuse of existing standards: EPOS-DCAT-AP.
Establishing Core Concepts for Information-Powered Collaborations


Managing distributed software development in the Virtual Astronomical Observatory
Iris, the VAO application for analysis of 1-D astronomical spectral energy distributions (SEDs) was successfully built and released in less than a year with a team distributed across four institutions and lessons learned will be folded into future development efforts.
The AstroGrid MySpace System
MySpace is AstroGrid's system for seamless remote access to archives and databases, implemented as a distributed network of co­operating web services that provides the astronomer with seamless access to a geographically dispersed work space.
Connecting the time domain community with the Virtual Astronomical Observatory
The issues involved with the heterogeneous collections of data associated with astronomical transients, and the time series characterization and classication tools required by the next generation of sky surveys, such as LSST and SKA are focused on.
Reengineering observatory operations for the time domain
The astronomical community is entering an era of rapid change increasingly characterized by large time domain surveys, robotic telescopes and automated infrastructures, and – most significantly – of operating modes and scientific consortia that span the authors' individual facilities, joining them into complex network entities.
Astronomical network event and observation notification
The current state of notification is explored, what notification requirements are essential to create a successful standard and a standard now under development by the International Virtual Observatory Alliance (IVOA), called the VOEvent is presented.
IRAF in the Nineties
A preview of what IRAF might look like to the user by the end of the decade is presented, with emphasis on the work being done on the image data structures, graphics and image display interfaces, and user interfaces.
Astropy: A community Python package for astronomy
We present the first public version (v0.2) of the open-source and community-developed Python package, Astropy. This package provides core astronomy-related functionality to the community, including
Sherpa: a mission-independent data analysis application
An overview of Sherpa's features is presented, which include: support for a wide variety of input and output data formats, including the new Model Descriptor List (MDL) format; a model language which permits the construction of arbitrarily complex model expressions; and new interactive analysis capabilities provided by embedding the S-Lang interpreted scripting language.
Constructing and Analyzing Spectral Energy Distributions with the Virtual Observatory
This research has made use of the NASA/IPAC Extragalactic Database which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the NASA.
