Deutsche National Bibliothek DNB

The Deutsche National Bibliothek DNB offers downloads of metadata of new publications. Metadata is delivered as MARC21 files. This service is free of charge. More details can be found here: Ongoing update of metadata

This documentation provides instructions for installing and using the marc21DB data
loader, including setting up the database, configuring the PHP files, and running
the script to load MARC21 data files.

DEMO

A fully working demo is located here:

https://vmd55223.contaboserver.net/marc21DB/

Dependencies

  • bulma css framework
  • fontawesome6

Refered to in the sources of classes/page.php

<link rel="stylesheet" href="/bulma/css/bulma.min.css">   
<link rel="stylesheet" href="/font-awesome-6/css/all.min.css">

Prerequisit

  • PHP 8.x
  • mySQL/mariaDB
  • bulma
  • fontawesome

Installation

Step 1

Download the source tree into your webspace.
Name the top level directory marc21DB

Load/execute the given marc21.sql.
This will create a database

  • marc21
  • fill table ddc with the code and description
  • create constraints for cascading delete

Step 2

In the directory marc21DB/include edit the file connect.inc.php in order to set the neccessary dbname , user and password for your database.

File adressPort.inc.php keeps adress of a websocket server to allow the backend to send feedback to the client If you are not using my phpWebsocketServer do not set $Address in there,

In the include Directory run

php ddc2DB.php

This will fill table ddc with code and description for language 'de' and 'en'

Step 3

In a shell/command line, step into director marc21DB/classe-get21. All files to download, read and insert data from marc21 files are located here. As a first test run

php getFiles.php -y 24 -w 01 -s A

This will download/load the file A2401utf8.mrc from the DNB.

Parameters are:

  • -y is the year as two digits (default is current year)
  • -w is the calendar week (default is current calendar week)
  • -s is the series you want to load

Upon succes the script will continously print out the internal id of the title loaded and the ddc associated with this title.

While loading from the file the table search is filled with the title author and publisher
in order to allow for fulltext search within these fields

Step4

Now you can call your URL adressing marc21DB

The GUI should come up and present you with the titles from the latest marc21 file and a facette with all the ddc found.

Full text search

Column what in table search holds text of marc21 fields for title,author,publisher. For this column a full text index is maintained allowing for fast full text search with titel or author od publisher.

To delete and recreate the table and index call maintain/buildFullText.php
