The fields of the Link Resolver Usage subject area can be used to create reports that provide both specific details of link resolver usage as well as a broad perspective of how the Alma link resolver is used. This provides libraries with a useful means of determining proper electronic collection development.
This subject area supplements the Usage Data subject area, which includes data from vendors, while the Link Resolver Usage subject area takes data directly from the Alma link resolver.
Using the Link Resolver Usage area, the Design Analytics you can create reports/dashboards for the Link Resolver Usage area and are able to answer the following types of business questions:
- How many times did users select View It in all sources over a specified period of time?
- How many times did users select View It in a specific source?
- How many times did users select View It and no results were produced?
- How many times did users select View It for a particular source that resulted in no full text?
- How many times did users select View It for the most frequently requested full?text journals from a particular source?

|Number of Requests Without Services||The number of incoming OpenURLs that do not result in any services|
|Number of Services (total)||The total number of services offered per incoming OpenURL request||The number of services offered per incoming open URL request both from:
|Number of Electronic Services||The number of electronic services that appear when a user selects View it||The number of electronic services that appear when a user selects View it.|
|Number of Digital Services||The number of digital representations that appear when a user selects View it||In order for this field to have data, you must select the Include Representation services in link resolver statistics check box (Configuration > Fulfillment > Discovery Interface Display Logic > Other Settings).|
|Number of Clicked Services (total)||The total number of services selected|
|Number of Electronic Clicked Services||The number of electronic services a user selects from the View it menu|
|Number of Digital Clicked Services||The number of digital representations a user selects from the View it menu.||In order for this field to have data, you must select the Include Representation services in link resolver statistics check box (Configuration > Fulfillment > Discovery Interface Display Logic > Other Settings).|
|% Clicks from Requests||The percentage of incoming OpenURL requests that were selected||% Clicks from Requests = (Number of selected requests / Number of Requests) * 100|
|% Requests Without Services from Requests||The percentage of incoming OpenURL requests that do not have services||% Requests Without Services from Requests = (Number of requests without services / Number of requests) * 100|
OpenURL Context Details
The OpenURL Context details table is a dimension table that stores the details of the OpenURL context object. The primary key is CONTEXT_OBJECT_ID. The context object is the part of the OpenURL that contains the metadata information that identifies the resource to which the OpenURL links.
|Title||The title of the OpenURL Context|
|Author||The Author of the OpenURL Context|
|ISSN||The ISSN of the OpenURL Context|
|ISBN||The ISBN of the OpenURL Context|
|Material Type||The Material Type of the OpenURL Context|
Network Inventory Group
|The network inventory group||This field allows you to filter and display link resolver usage by library or campus. This is relevant for institutions using the inventory network groups.|
|Request ID||The Request ID of the OpenURL Context|
|Article Title||The Article Title of the OpenURL Context|
|EISSN||The EISSN of the OpenURL Context|
|Source||The Source of the OpenURL Context||The database/index that generates an OpenURL to the link resolver in order to obtain context-sensitive services for an electronic resource citation/reference.|
|Normalized Source||The normalized name of the source.|
|Open URL||The OpenURL|
|Source Type||The Source Type||
This field allows libraries to easily gather data about from where users are coming when using the Alma Link Resolver.
The following are the possible values for the Source Type field:
The Source Field
The Source field indicates is the database/index that generates an OpenURL to the link resolver in order to obtain context-sensitive services for an electronic resource citation/reference. It appears in the OpenURL after the dash—for example, after &rfr_id=info:sid/primo.exlibrisgroup.com-. It also appears in the Primo PNX record.
By comparing the Source with other parameters such as Number of Clicked Requests, you can analyze trends in the use of electronic resources.
The following are some guidelines that indicate how the source is determined:
- If a patron selects on a title in Primo that is in Alma, the source is the source ID of the system.
- If the source has a colon in it, either the user was a staff member testing the link within Alma, or the user received access to an article from within a database by being referred back to the uresolver to see if the user has a subscription that covers it.
- If the source has an underscore or consists of letters such as wj (Wiley journals), the user received access to the article from a PCI record in Primo.
The source google does not have a colon and means Google Scholar.
The following is an example of an OpenURL with the source and other fields of the OpenURL Context Details table in bold:

|Group5||Stores the name of the fifth level|
|Classifications||Stores the Hierarchy column that allows the user to drill down from the first level of the classification to the fourth level. Using this column provides the user with the option to view the accumulative measures. Note that the fifth level is not included in this field.|
For a Knowledge Article related to LC Classifications, see Analytics LC Classification code shows Unknown even though a call number is present in Alma.
Books can be classified with Dewey Classifications.
In Dewey Classifications, topics are ordered in a hierarchy that is indicated by a three digit number. The highest level of the hierarchy is indicated by a number with one significant digit followed by two zeros, such as 600. The second level in the hierarchy is indicated by a number with two significant digits followed by one zero, such as 630. The third level in the hierarchy is indicated by a number with three significant digits such as 636.
The field descriptions can be found in the Dewey Classifications shared dimension.
|Dewey Number||Holds the first 3 digits of the Dewey Classification.||
The Dewey Number comes from the bibliographic record, except for in the Physical Items subject area where it comes from the holdings record.
|Group1||Stores the name of the first level.|
|Group2||Stores the name of the second level.|
|Group3||Stores the name of the third level.|
|Dewey Classifications||Stores the Hierarchy column that allows the user to drill down from the first level of the Dewey Classification to the third level. Using this column provides the user with the option to view the accumulative measures (loans or returns) in each level of the hierarchy.|
The Other Classifications table is a dimension table that contains fields for classification systems other than LC and Dewey.
|Classification Code||The Chinese Classification code with which to find a match to the Chinese Classification code from the bibliographic record.|
|Group 1-7 (Chinese)||Stores the Chinese Classification Code, which comes from the bibliographic record.|
|Group 1-7 (English)||Stores the name of the levels of classification|
The shared Institution dimension allows the Network Zone to view reports according to institution. It is available in every subject area. It contains the following fields:
|Institution Code||The code of the institution.|
|Institution Name||The name of the institution.|
|Institution Timezone||The timezone of the institution|
|Data Available As Of||When the data became available to analytics|
|Data Update As Of||When the data was taken from Alma|
If an analytics report is run from the Network Zone in a collaborative network implementing a Network Zone, all member institutions are included in the report for Institution Code and Institution Name.
If an analytics report is run from an institution that is not part of a collaborative network implementing a Network Zone, only the single institution from which the report is run is included in the report for Institution Code and Institution Name.
Reports involving data across a collaborative network implementing a Network Zone may take longer to run than reports within one institution.
