Time Series, Collaboration and Large Data Sets Enhancements of SPLAT-VO

Virtual Observatory (VO) is a world-wide ecosystem of mutually compatible datasets, resources, services, and~software tools which use a common set of technologies and~standards. SPLAT-VO is a leading stellar spectra analysis tool that allows displaying, modifying and~analyzing astronomical spectra. SPLAT-VO also serves as a reference implementation of new VO protocols and data models and~is~being enhanced in a way of interaction with other tools and~collaboration, as well as user experience. Our enhancements of SPLAT-VO allows to send large data sets received from VO data archives to other tools via SAMP protocol, export spectral data to Big Data-friendly formats and to work with light curves in VOTable data cube format. There is also a preview of other enhancements that significantly improves the user experience with large data sets and lowers the memory consumption of SPLAT-VO.
