Vufind: delete imported records

Vufind admin panel ( allows to delete records by id (it calls Records.php, and more precisely the deleteRecord method).

But if you want, for instance, to delete all records from a bad import you can do it directly from your system prompt using util/delete.php script:

The first parameter is the import file name and the second, its format. If no format supplied, ‘marc’ is assumed.

php util/deletes.php import/400.mrc marc

In my case an error was showing up:

PHP Warning:  parse_ini_file(../web/conf/config.ini): failed to open stream: No such file or directory in /usr/local/vufind/util/deletes.php on line 48
Warning: parse_ini_file(../web/conf/config.ini): failed to open stream: No such file or directory in /usr/local/vufind/util/deletes.php on line 48
Solr index is offline.

Mmmhh. Relative path issues.

I opened deletes.php and edited line 48 so that parse_ini_file is done to /usr/local/vufind/web/conf/config.ini (full path). But then another error was showing up:

PHP Fatal error:  Call to a member function getData() on a non-object in /usr/local/vufind/util/deletes.php on line 85
Fatal error: Call to a member function getData() on a non-object in /usr/local/vufind/util/deletes.php on line 85

What’s the problem now? Well, I am NOT USING MARC’s 001 tag as identificator as stated in my import/ (which overrides import/ My id is set to record’s 907a tag value… UG.

We will cope with this issue later (here!)

New delete tool script

I first decided to make a little php program which allows me to delete a list of identifiers. I called it util/BorraRegistros.php.

This php script is called WITHOUT parameters, so you’ll have to edit it in order to include the identifiers in $lista_ids_registros array.

require_once 'Solr.php';
$configArray = parse_ini_file('/usr/local/vufind/web/conf/config.ini', true);
// Setup Solr Connection
$url = $configArray['Index']['url'];
$solr = new Solr($url);
if ($configArray['System']['debug']) {
    $solr->debug = true;
// ----------------------------------------------------------------
// This is the list of SOLR IDENTIFIERS to be deleted!!!
$lista_ids_registros = array('.b1000001x');
// ----------------------------------------------------------------
print "Interfaz de borrado de registros\nSe borraran los registros cuyos identificadores son:\n";
// Confirm deletion...
echo "¿Seguro de que deseas continuar? Escribe 'si' para continuar: ";
$handle = fopen ("php://stdin","r");
$line = fgets($handle);
if(trim($line) != 'si'){
    echo "Cancelado\n";
echo "\n";
echo "Gracias, se va a proceder...\n";
// Delete each record identified by its value $lista_ids_registros
foreach ($lista_ids_registros as $id_registro){
   print "\nPreparando para borrar el registro '$id_registro'.............................";
   print "[ OK ]";
print "\nTerminando el borrado...";
// Now commit and optimize
print "\n";

More references to SOLR delete by id in

This script could also be done using cURL, but I kinda prefer it this way.

Fixing util/delete.php to fit records identified by marctags distinct from 001

Above we noticed problems when deleting recently imported records with util/delete.php. The problem is that this script does not read import/ and therefore does not notice that our solr records might not be identified by its marc’s 001 tag.

For instance, in my import/ we find:

id = 907a, first

So I modified util/delete.php so that it takes into account that my solr records are identified by tag 907 (subfield ‘a’) AND not tag 001! Notice changes in lines 86-90.

Now we can run the new script and it will work 🙂

vufind: mostrar información de reservas en los registros

Estos días he estado trasteando con vufind ([1] y [2]).

Mostrar el enlace hacia Holds

En algunas bibliotecas que también tienen vufind y su catálogo es Innovative Millenium había visto que mostraban la posibilidad de colocar un enlace para reservar ejemplares directamente. Sin embargo en mi instalación de vufind no parecía funcionar.

Investigando un poco en la wiki de vufind descubrí que el fichero que me estaba “fastidiando” era el view-holdings.tpl y más en concreto estas líneas:

 {foreach from=$holding item=row}
    {if $row.barcode != ""}

Mis registros no tenían un valor de barcode asignado, por lo cual esa parte del código no se ejecutaba.

¿Cómo lo averigué? Colocando un print_r de la variable $row en smarty (cómo hacer print_r de arrays en smarty templates). Mi código de view-holdings.tpl ha quedado ahora asi:

 {foreach from=$holding item=row}
    <em> Edit view-holdings.tpl by MiguelMartin</em><br />
    <!-- comento esta linea y añado la siguiente -->
    <!--if $row.barcode != ""-->
    {if $ != ""}

Como todos mis registros sí tienen ID, el código se ejecuta y se muestra el link.

Que viva el open source! 🙂

(Para saber cómo configurar la conexión entre vufind y tu software de catálogo puedes consultar éste link)

Hacer que funcione el enlace a Holds usando Innovative

El link que se genera con lo anterior es del tipo

Si usamos el driver de Innovative que viene por defecto (la pareja de archivos Innovative.ini y Innovative.php) obtendremos un error de PEAR que dice algo asi:

Cannot Process Place Hold - ILS Not Supported

Este error viene de $VUFIND_HOME/web/services/Record/Hold.php.

Para solucionarlo cambiad vuestro Innovative.ini por algo del tipo (ojo, cambiad la ‘url’ de la sección [Catalog] y de [PATRONAPI] para que apunte a la url de vuestro catálogo):

url =
; The following is a set of fields to look up for
; Change them to match your HTML
location_column    = "Location"
call_no_column     = "Call No"
status_column      = "Status"
reserves_column    = "Location"
reserves_key_name  = "res"
status_avail       = "AVAILABLE"
status_due         = "DUE "
; "bib" or "item" level holds
holdtype = "bib"
; Enable III Patron API usage for patron authentication
; and profile information.
enabled = "true"
url =

Vufind con Innovative Millenium y CDS-Invenio: importar registros y configurar facetas

Unos días atrás comenté cómo instalar vufind.

Una vez instalado el software y comprobado que funcionan algunos aspectos fundamentales (como la validación por LDAP, etc), el siguiente paso es proceder a la importación de registros (bien sean desde el Catálogo de la Biblioteca o desde Repositorios OAI).

Paso a comentar algunas conclusiones obtenidas mediante las primeras experiencias de carga.

Carga de registros de prueba procedentes de Innovative Millenium (formato MARC)

Imaginemos que hemos exportado desde Millenium un archivo con registros MARC (.mrc). En caso de que no tengáis una exportación de registros a mano podéis usar (esta página o ésta otra para obtener datos de ejemplo).

Mi fichero se llama $VUFIND_HOME/import/400.mrc

Procedo a importar los registros con la siguiente orden:

/usr/local/vufind/ import/400.mrc

Más información en la wiki de vufind.

Carga de registros de prueba procedentes de CDS-Invenio (formato MARCXML)

Imaginemos que exportamos de un repositorio un conjunto de registros en formato marcxml, por ejemplo éste.

Creo una carpeta para almacenar estos ficheros .xml exportados:

mkdir $VUFIND_HOME/harvest/desdezaguan
mkdir $VUFIND_HOME/harvest/desdezaguan/marcxml
cd $VUFIND_HOME/harvest/desdezaguan/marcxml

Obtengo los registros…

Cambio el nombre del fichero xml…

 mv search\?as\=1 tesis0.xml

Y procedemos a realizar la importación. Se invoca poniendo como parametro el directorio donde están los XML’s:

[root@ harvest]# cd /usr/local/vufind/harvest; \
                     ./ desdezaguan-tesis/marcxml/

La invocacion MUEVE el fichero tesis0.xml y crea:

harvest/desdezaguan/marcxml/log y

Veamos qué tiene cada carpeta:

[root@ marcxml]# ls -l $VUFIND_HOME/harvest/desdezaguan/marcxml/log/
total 8
-rw-r--r-- 1 root root 3095 Sep 29 12:54 tesis0.xml.log
[root@olmo marcxml]# ls -l processed/
total 68
-rw-r--r-- 1 root root 59068 Sep 29 12:49 tesis0.xml (el original)
[root@olmo marcxml]# cd log/
[root@olmo log]# more tesis0.xml.log

*** NOTA: Si el identificador del registro YA EXISTE en vufind no duplica, actualiza el registro

Configurando el display name de las facetas solr en vufind

Las facetas se describen en el archivo facets.ini. Os muestro cómo queda nuestro archivo tras la modificación y customización de los nombres que se mostrarán en las facetas. La parte de la izquierda muestra el ‘nombre lógico’ del índice de SOLR y la parte derecha el display name (aka ‘lo que sale en la web como facetas’).

* Nota: funcionan las tildes perfectamente (thanks vufind guys!)

more $VUFIND_HOME/web/conf/facets.ini
; The order of display is as shown below
; The name of the index field is on the left
; The display name of the field is on the right
institution        = Origen
building           = Localización
format             = Formato
; Use callnumber-first for LC call numbers, dewey-hundreds for Dewey Decimal:
callnumber-first   = "Call Number"
;dewey-hundreds     = "Call Number"
authorStr          = Autor
language           = Idioma
genre_facet        = Genero
era                = Era
geographic_facet   = Región

; recommendations module is used.  See the [TopRecommendations] section of
; searches.ini for more details.
topic_facet        = "Suggested Topics"
; This section is reserved for special boolean facets.  These are displayed
; as checkboxes.  If the box is checked, the filter on the left side of the
; equal sign is applied.  If the box is not checked, the filter is not applied.
; The value on the right side of the equal sign is the text to display to the
; user.  It will be run through the translation code, so be sure to update the
; language files appropriately.
; Leave the section empty if you do not need checkbox facets.
; NOTE: Do not create CheckboxFacets using values that also exist in the
;       other facet sections above -- this will not work correctly.

Los nombres de las facetas quedarán tal que asi:

Asignación de valores a las facetas solr en vufind

Es el próximo paso que queremos dar. Pero antes observemos cómo podemos hacer consultas al motor SOLR de vufind.
En de tu servidor web podemos ver una amigable interfaz que nos permite consultar cómo son las respuestas XML a peticiones de consulta del motor y, de este modo, hacernos una idea de cómo queremos asignar valores a cada una de las partes.

Interfaz de consultas a SOLR:
vufind solr web interface

Haced una query. Ver cómo es el XML que devuelve. Fijaos en los valores que tienen los distintos registros devueltos en cada campo. En concreto, y para enseñarlo siempre con un ejemplo, vamos a fijarnos en el campo institution, que por defecto tiene asignado siempre el valor estático ‘MyInstitution’ para cualquier registro importado:

<arr name="institution">

Esto es debido a la siguiente línea del fichero $VUFIND_HOME/import/ donde a esa faceta se le asigna el valor estático ‘MyInstitution’:

institution = "MyInstitution"

Imaginemos que queremos que la faceta ‘institution’ haga referencia al origen de los datos. Tendremos varios orígenes distintos: catálogo y repositorio.

Queremos que, si el registro viene del repositorio (Esto es, tiene 980a==’TESIS’) en esta faceta se guarde la cadena “Repositorio”.
Para ello debemos editar el fichero (este fichero sobreescribe los settings por defecto marcados en

vi $VUFIND_HOME/import/

Y añadimos la siguiente línea:

#asignar a la faceta 'institution' el valor de la etiqueta 980a según el <em>mappeo</em> establecido en el fichero <em></em>
institution = 980a,

Y el contenido del fichero $VUFIND_HOME/import/ es:

[root@ import]# more /usr/local/vufind/import/
# Si el valor de la etiqueta marcxml es 'TESIS', asigna a la faceta la cadena 'Repositorio'
TESIS = Repositorio

Del mismo modo imaginemos que, si el registro viene del catálogo (Esto es, tiene 907a==’.b1XXX’) en esta faceta se guarde la cadena “Catálogo”. En el fichero $VUFIND_HOME/import/ pondremos la línea:

# Tomamos los caracteres 1 y 2 de la etiqueta 907a y los <em>mappeamos</em> según el fichero <em></em>.
institution = 907a[1-2],

Y en

[root@olmo import]# more /usr/local/vufind/import/
b1 = Catalogo

¡Mucho ojo con los caracteres especiales como el punto (.) pues son interpretados como expresión regular y habría que escaparlos!

También es útil asignar el campo que actuará como identificador de los registros en vufind. En nuestro caso deseamos utilizar el valor de la etiqueta 907a como identificador del registro. Como la etiqueta es repetible deberemos añadir también el modificador first.

Añadimos pues la siguiente línea a

id = 907a, first

Acordaos de reiniciar vufind tras estas modificaciones:

$VUFIND_HOME/ restart

De momento os dejo con el manual de facetas de la wiki de vufind para que sigáis leyendo 😉

Más experiencias en breves!
