               INTRODUCTION

 In this issue, Gail Schneider summarizes the results of May 2000 ADC User
Survey.  Our thanks go to all who participated in that survey.  It has helped
us to focus on what matters most to you, the users that we serve.


 Also in this issue, we highlight the progress to date on the ADC's XML
activities.  This project is already paying benefits to the ADC and to other
groups.  If you are unfamiliar with XML and our work to apply it to scientific
data, please ready this article and check the related web pages.


 As always, thanks to those who visited our exhibit booth at the soggy San
Diego meeting of the American Astronomical Society earlier this month.  Like
the user survey, those interactions at scientific meetings help to keep us in
touch with your needs, important new data sets, and how we can improve our 
services.

               Results of the ADC User Survey
Gail L. Schneider (Raytheon ITSS)  In our May 2000 issue we put together a few questions on the relevancy of our services pertaining to your research work. Those responding gave beneficial and favorable answers.  Most of the respondents were professional astronomers/physicists using both the ADC Data Viewer and VizieR for research purposes. The catalog collection was the top "very useful" and "weekly accessed" service for all respondents, followed by the published journal tables.  Well over half of the respondents have found the ADC services have assisted them with research work and significantly decreased the hours of effort to complete their work. As a result of using the ADC services in the development of new ideas for research projects, 11% of the respondents said it led to published work or presentations and 4% said it led to funded grant proposals.  About half of the respondents were very interested in the ADC providing enhanced data discovery, while nearly as many desired greater access to very large tables, serving all data from major journal publications, and cross correlation of tables. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * XML Work Progresses at the ADC
Ed Shaya, Brian Thomas, James Gass, James Blackwell, Gail Schneider, Nils Odegard (Raytheon ITSS), Tom Sodroski (SM&A), Cynthia Cheung (NASA/GSFC)  The entire staff of the Astronomical Data Center (ADC at GSFC/NASA) is involved in research into the application of eXtensible Markup Language (XML) for the repository of published astronomical data. Automated pipelines have been developed for the flow of data from scientists and journal presses into XML documents. The goal of these pipelines is to greatly reduce the human effort required to transform electronic human-readable tables into machine-readable and database-ready documents. This will allow us to make more tables available with shorter ingest times. An important benefit is that the resulting XML documents can be searched by detailed or complex query using the latest XML-based search tools that we will soon make available. For demos of this see http://tarantella.gsfc.nasa.gov/xml and click on search demos.  The ADC has also developed a new general data format designed to take full advantage of the XML hierarchical structure, while retaining full use of the standard keywords and parameters in FITS. The mathematical core of the format is XDF, the eXtensible Data Format. (See the XDF web pages at http://tarantella.gsfc.nasa.gov/xml/XDF_home.html). When FITS keywords are layered over this core it is called FITSML.  With XDF, it is possible to layer keywords from any scientific field to create new XML data formats. For data placed in this format, information on the structure of the data, axis information and other metadata are searchable by XML standard tools. We have created an Application Programming Interface (API) for programs to easily read, write, edit, and interact with the data and metadata of XDF. Beta level versions of both the Perl and Java versions of the API can be obtained from http://xml.gsfc.nasa.gov/ADCSoftwareDownload.html.  The ADC invites scientists and programmers to comment on the design and standards set by the Document Type Definitions (DTD) that describe XML languages XDF and FITSML. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Newly Acquired and Updated Catalogs/Journal Tables
Gail L. Schneider (Raytheon ITSS)  The following catalogs and journal tables are currently available from the ADC repository. The ADC gratefully acknowledges the CDS, and individual authors who have recently contributed to our repository.  See http://adc.astro.umd.edu/adc/acq_new_updated.html#new_list for a hypertext version of this article containing direct links to each catalog and journal table listed.   NEW CATALOGS AND JOURNAL TABLES ID# Abbreviated Title (First Author, Year) Astrometric and Positional Data 1260 Visual Double Stars in Hipparcos (Dommanget+, 2000) 1265 Second Cape Photographic Catalogue (CPC2) (Zacharias+, 1999) 1266 Proper motions of fundamental stars (PMFS) (Gontcharov+, 2001) Photometric Data 2231 A Finding List of Faint UV-Bright Stars (Lanning+, 2000) Spectroscopic Data 3076A Luminous Stars in the Northern Milky Way (LS) (Hardorp+ 1959-1965) Nonstellar and Extended Objects 7156A Catalog of Pulsars (Taylor+ 1993) 7214 APS Galaxies in the North Galactic Pole (Cabanela, 1999) 7219 Revised Flat Galaxy Catalogue (RFGC) (Karachentsev+, 1999) 7220A Barnard's Catalogue of 349 Dark Objects in the Sky (Barnard 1927) 7221 PSCz catalog (Saunders+, 2000) Radio Sources 8045 Southern flat-spectrum sources (White+ 1991) 8064 Westerhout's Catalogue of 82 Discrete Sources (Westerhout 1958) 8063 ATESP radio survey.
