The BibCat is a ombination of a database and tools for populating and a essing the data.
The database provides exibility to the lassi ation pro ess. This is key to maintaining abibliographi atalog.

Re ordClassify papers:

Classi ation of papers requires people to peruse papers and then re ord
their judgments in the database.

S an paper:

The onverted papers need to be s anned for auto-elimination; meta-dataolle tion; and possibly for a rst guess at lassi ation

Papers are generally pdf or html. Converting the pdf's to text poses anumber of problems with both text- ow issues and s anned image papers.

Download papers:

The method for getting the papers is publisher dependent and requires
a library of ode to a ess their holdings.

To allow for the exibility needed in the requirements, the database tables fall into three ategories: 1) tables des ribing the physi al publi ation in luding publi ation date, publi ation
type, refereed, title, authors, keywords, and links to other papers (blue box); 2) tables des ribing the data enter meta-data olle tion in luding de nitions of the ategories and ags
atta hed to papers (green box); and 3) tables re ording the lassi ation of papers by individual lassi ers (purple box).

A knowledgment:The usefulness of some of these features speak for themselves, but others are not soobvious. As an example, we intend to use the multi-observatory fun tionality to apply
separate lassi ation s hemes to papers relating to the CDA and the Chandra Sour eCatalog and potentially to other observatories at the Center for Astrophysi s. The data
mining aspe ts of the auto-s anning apabilities an be used for many purposes su h as:
improving sear hing for Chandra related papers from both ADS and our bibliography sear hpages or linking papers to grants for internal uses.

The BibCat was designed to a omodate two goals of the CDA regarding Chandra-related
papers: tra k papers for Chandra s ien e statisti s and ag information in papers forresear h purposes.

The Chandra Data Ar hive (CDA) has been tra king publi ations in refereed journals andon-line onferen e pro eedings that are based on Chandra observations sin e early in themission. Over the years this database and its asso iated tools have expanded dramati ally.
In this paper we des ribe our newly renovated bibliography ar hite ture with an emphasis
on new features whi h have been added in luding: auto-s an apabilities to redu e in an
automated fashion the number of papers whi h need to be manually lassi ed and to ag
keywords (su h as observatory names or surveys) used within papers; multi-user lassi ation allowing quality assuran e he ks; multi-observatory apabilities allowing multiple
fa ilities to use the same database independently; and plug-in support allowing a ess toasso iated observatory data to more fully des ribe data links in papers.

We use the ADS as our sour e for all potential publi ations, rather
than going to ea h publisher independently. We need to retrieve new bib odes anda ount for bib odes whi h have hanged names or have been retired from ADS.
