Outline Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • • • Introduction Motivation Astro. Cat CVcat Demo Connecting scientists and libraries

Astronomical Catalogs - History Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • First catalog by Hipparchos (180 -125 b. Chr. ) 1022 stars (position and brightness) • Continued by Ptolomäus and numerous astronomers into modern times • Argelander (1799 -1875) all (northern) visible stars, a survey using a 10 cm telescope (22000 objects) variable stars • Catalog by Messier (1730 -1817) nebulous objects not to be confused with comets (107 objects)

Astronomical Catalogs - Present Interactive Catalog Introduction Motivation • Today: 6453 catalogs listed e. g. @ Strasbourg Astronomical Data Center Astro. Cat CVcat Demo Libraries • Bibliographic data base with 4. 6 M entries @ Smithsonian/NASA Astronomical Data Center • Preprint Server, e. g. astro-ph @ ar. Xiv • Several Virtual Telescope Projects, e. g. MAST (Multi Mission Archive at Space Telescope)

Motivation for interactive catalogs Interactive Catalog From data to paper Introduction Motivation Astro. Cat CVcat Demo Libraries • • Raw data Reduced data Derived quantities Publication Data Archive ? Bibliographic Archive

TRIPP

Current and Future Challenges Interactive Catalog • Dedicated survey telescopes Introduction Motivation Astro. Cat • Larger CCD cameras CVcat Demo Libraries • E. g. Pan-STARRS with few Tbytes/night

Motivation for interactive catalogs Interactive Catalog From paper to (meta-)data Introduction Motivation Astro. Cat CVcat Demo • Statistical analysis of available data • Planning of observations Libraries • Data base query of derived quantities

Requirements Interactive Catalog Introduction Motivation • Complete • Error free Astro. Cat CVcat Demo Libraries • Up to date • citable • Catalog from the community for the community Web based Interactive • Astro. Cat provides a platform for the implementation of such catalogs

Technical details Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • • Linux Postgre. SQL PHP 5 XML (Astro. Cat. ML)

The Team Interactive Catalog • Original Idea: Boris Gänsicke, Jens Kube (Institute for Astrophysics, Göttingen) Introduction Motivation Astro. Cat CVcat Demo Libraries • Movement towards a more general project in library context: Klaus Beuermann (IAG), Elmar Mittler (State and University Library Göttingen) • Design and definition: Fabian Euchner, Alexander Pollmer • Extended phase: Stefan Dreizler, Ralf Stockmann • Implementation CVcat: Fabian Euchner, Alexander Pollmer, Boris Gänsicke (now: Univ. of Warwick)

CVcat – a catalog of cataclysmic variables Pspin=833 sec

Input: What’s known Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo • • Astronomical coordinates Object name(s) general astronomical Brightness Classification Libraries • Stellar parameters • System parameters CV special

Output: CVcat provides … Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • Query by – – Name Coordinates Classification Object properties • Returns – List of objects (in user definable formats) – Overview of properties for all objects

Community involvement in CVcat Interactive Catalog Introduction Motivation • Unregistered user: everybody – Query the data base Astro. Cat CVcat Demo Libraries • Registered user: about 200 – Add properties and new objects – Add comments • Editors: a few – Guarantee correctness – Massive data input

Connecting scientists and libraries Interactive Catalog Introduction Motivation • Interesting aspects for librarians: – Long-term citation of dynamic web-pages Astro. Cat CVcat Demo Libraries change history / logfile

Connecting scientists and libraries Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • Interesting aspects for librarians: – Collaborative work spaces – Supporting infrastructure for knowledge management and sense-making • Adopt tools for other astronomic objects – Provide a portal

EZOOLO – Early Zoological Literature Online Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • Provide free access for all scientists to the old zoological literature • Literature is digitized in image format by the SUB Göttingen (Göttinger Digitization Centre) • Collaborators have the right to enter data directly into the database

RMC – Rise of Modern Constitutionalism Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • Create a scholarly edition of all constitutions that were part of the rising tide of modern constitutionalism between 1776 and 1849 • Offering both digitized images and fulltext • Supported by more than 30 contributors responsible for the constitutional documents within their regional and topical area of specialization

RMC – workflow Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • Minimal standard in text editing: Microsoft Word • Fully automated workflow: – M$ Word macro (incl. “submit button”) – Upload to RMC-Server and conversion into Open Office XML – XSLT-script to transform the text into TEI (Text Encoding Initiative), well defined, well structured, well tagged (indices) – Upload to web server
