Query languages for domain specific information from PTF astronomical repository

Abstract

The increasing availability of vast amount of astronomical repositories on the cloud has enhanced the importance of query lan- guage for the domain-specific information. The widely used keyword- based search engines (such as Google or Yahoo), fail to suffice for the needs of skilled/semi-skilled users due to irrelevant returns. The domain specific astronomy query tools (such as Astroquery, CDS Portal, or XML) provide a single entry point to search and access multiple astronomical repositories, however these lack easy query composition tools in unit-step or multi-stages query. Based on the previous research studies on domain- specific query language tools, we aim to implement a query language for obtaining the domain-specific information from the astronomical repos- itories (such as PTF data).
