Primo Glossary of Terms

Term	Definition	In III	In Voyager
Alerts	You can save a search query, and have the search set to be performed automatically. An alert notifies you if there are any new search results.
Availability pipe	The availability pipe checks for available updates several times throughout the day.
Availability text	This text is determined by Primo. It appears next to the item name and indicates to the user the availability of the resource.
Back Office	The user interface and programs that manage the Publishing Platform.
Basic Search	A configurable tile in the Views wizard. The user uses this tile to search for a specific item.
Brief Results	A configurable tile in the Views wizard. After the user searches for a specific item, the results appear in this tile.
Bulks	The publishing pipe process records in groups of records that are called bulks. By default, the bulk size is 1000 records.
Data source	The data source from which the Publishing Platform harvests records. A single source system may contain several data sources. For example, in terms of SFX, Primo harvests a single SFX instance. A single SFX installation may include several instances (that is, data sources). In Aleph and Voyager, every bibliographic database is a separate data source. A single installation of Aleph or Voyager may include several bibliographic databases that are harvested by Primo.
Delivery restricted scopes	Restricted delivery scopes indicate access restrictions for online resources.
Double metaphone	The double metaphone search algorithm is a phonetic algorithm and is the second generation of the metaphone algorithm. It is called "double" because it can return both a primary and a secondary code for a string. For example, encoding the name "Smith" yields a primary code of SM0 and a secondary code of XMT, while the name "Schmidt" yields a primary code of XMT and a secondary code of SMT. Both have XMT in common.
E-shelf	E-shelf lets you save search results in your Basket.
Facets	A configurable tile in the Views wizard. The tile opens relevant links that might interest the user, determined from the search that was made.
Institution	The institution is a central administrative concept in Primo. Users and resources belong to institutions.
Main pipe	The main ILS pipe is generally run during the night and includes all updates to bibliographic records and related holdings and authorities.
Metaphone	Metaphone is a phonetic algorithm for indexing words by their sound, when pronounced in English. The algorithm produces keys as its output. Similar sounding words share the same keys and are of variable length in the metadata form.
n-gram	An n-gram is a sub-sequence of n items from a given sequence. n-grams are used in various areas of statistical natural language processing and genetic sequence analysis. The items in question can be letters, words, or base pairs, according to the application.
Normalization mapping set	The set of normalization rules that convert source records to the PNX.
Normalization rule sets	Normalization rules are applied to the source data. These rules are used to translate the data source into a PNX format.
PDS	The Patron Directory Service is used with all Ex Libris products as a user authentication system.
Persistence layer	An Oracle database that is part of the publishing platform in which PNX records are stored before they are retrieved by the search engine.
Pipe run	Every execution of a publishing pipe is called a pipe run
Pipes	The pipe is the set of steps that the source information goes through before being turned into the PNX record.
PNX	The Primo normalized XML format. This is the common format to which all source records are converted.
PNX record	Primo normalized XML record. The source record is translated to this format and loaded into the Primo database.
Publishing pipe	Within the Publishing Platform, PNX records are created by publishing pipes. In principle, every data source has its own pipe with its own normalization mapping set.
Restricted search scopes	By defining restricted search scopes, you can restrict discovery of groups of records to specific users.
Scopes (Views)	Scope is a general concept that is used to create groups of resources. Primo has three types of scopes: o Search scopes o Restricted search scopes o Restricted delivery scopes The term “scope” is also often used to refer to search scopes, which are defined per view.
Search scopes	Search scopes are defined per view and define a group of record that can be searched together. There are two types of search scopes: o A local scope is a subset within the Primo repository. The default is the entire local repository. o A remote scope is a list of records in a remote location outside the Primo repository.
Similar items	You can create a search for similar items. Similar items creates a search based on the author of the item from the previous search.
Slice	The Primo Search Engine supports multiple slices to reduce retrieval time for very large data sets.
Source record	The individual record from the data source that is converted to the Primo normalized record (the PNX).
Source system	The system from which the Publishing Platform harvests records —for example, Aleph, Voyager, and SFX.
Tagging	Users can add reviews and keywords to any item.
View	The View is the Primo user interface. You can define one or more view. Every view can have a different “look and feel” and list of search scopes.
