Angular supports a rich component model which allows us to consume and create reusable libraries. In this post, we'll first show how to use a component to select entities, and then we'll walk through how we built the component. Using the Select Entities Component We've started with a brand new Cloud App. Following the instructions…

The Appointment Scheduler Cloud App has been used by institutions to schedule thousands of appointments in their libraries. It's a great way to leverage the Alma platform to provide library-related functionality, and has been especially useful as many libraries are providing service remotely or by-appointment only. The Cloud App supports defining locations and capacity, scheduling…

We've mentioned JWT tokens in several previous blog posts. According to jwt.io, JSON Web Tokens are "an open, industry standard method for representing claims securely between two parties." A quick Google search produces many good websites and videos that describe how these tokens work. And because JWTs are an open Internet standard, there are libraries…

Often when building apps for our users there is a need to host a back-end API. Public cloud offerings make hosting APIs easy and affordable. In a previous post, we used the services of the AWS public cloud to host an API. In this post, we'll learn how to use the AWS API Gateway and…

Webhooks were introduced several years ago and are a great way to have Alma notify you when events happen the system. We continue to see increased webhook usage - last month Alma sent almost 20 million webhook requests! In previous blog posts, we've seen how to develop a webhook listener locally. In this post, we'll…

The Alma configuration and administration APIs are quite powerful and enable advanced orchestration workflows. We've shown how to use the APIs in previous blog posts. In this post, we will show how to use the create set API to create a complex logical set with multiple conditions. The Developer Network contains documentation on the logical…

The Cloud App framework provides the ability for an app to persist data at the user (settings) or institution (configuration) level. The data is stored as a JSON blob and thus can contain standard JavaScript types such as strings, numbers, booleans, and arrays. But what if the developer wishes to provide the opportunity to store…

Alma supports the loading of digital materials via CSV files. MD Import profiles can create bibliographic records, representations, and digital files. The workflow involves creating a CSV file in the supported format with metadata and file information, uploading the CSV and digital files to the appropriate folder in S3, and running the MD import process.…

Most data-manipulation applications have some requirement to limit a form field's value to a controlled list of options. In this case, it's beneficial to have a way to obtain the acceptable values in order to provide a user interface which offers a select box, radio buttons, or check boxes. In our example, we're building a form…

One of the powerful features of Cloud Apps is the ability to make API requests in the context of the current user. This means that no API key is required and the user's privileges are considered when determining which APIs are accessible. In a consortial setting, there is often a need to retrieve or update…

While building a Primo customization package, the need arose to call the Alma Resolver from JavaScript. As we've discussed before, most APIs and services don't support CORS as a security best practice. To work around this limitation, we can configure a proxy which adds the required CORS headers. In this post, we'll show an option…

Last year we launched the Ex Libris App Center, an online marketplace on the Ex Libris Developer Network for publishing and searching for apps which extend or integrate with Ex Libris products. Community developers and partners have shared more than 60 apps that users can find and download. Today, we're announcing the next leap in…

In a previous blog post, we described how to use the Swagger Codegen toolset to build full client SDKs for the Alma APIs. In this post, we'll show how to customize the output of the tool to fit the needs of your workflow. Specifically, we'll perform the following tasks: Download and build the source of…

Many institutions have integrated Alma with their campus ERP system. Using the file-based or API-based integration, it's possible to send invoices which are ready for payment to the ERP system to be processed, and to receive payment confirmation back when the invoice has been paid or rejected. In some cases, the ERP system requires that…

In a previous blog post, we created a simple linked data-powered author card using the Alma Linked Data APIs. In this post, we'll create a Primo customization widget which integrates the author card into the Primo full view. Our author card uses the Bibcard library made available by the University of Wisconsin at Madison. The…

Authentication is one of the most critical integrations between Alma and Primo and the university infrastructure. We continue to invest in authentication options to remain up to date with industry standards, to provide a secure platform, and to fill the integration needs of a wide array of institutional authentication landscapes. In this post, we’ll review…

Several of the Primo REST APIs operate in the context of a user. Those APIs require that the caller send in a token which represents the user’s context. This post lays out the steps required to create the token and use it in subsequent API calls. Create the Token To create the user token, you…

We are in the age of single-page web applications (SPAs). A SPA loads in a user’s browser and sends requests to the server to bring or update data. Rather than returning to the server to receive new HTML, the user interface is updated dynamically based on the data retrieved. The rise of frameworks for JavaScript…

In a previous blog post, we explained the rationale behind offering discovery-optimized APIs. In a recent Alma release, additional support has been added to take display logic rules into consideration when calculating request options for a title. Check out "Discovery-Optimized APIs: Requests and Request Options" for an introduction to the request options API. In this post…

Earlier this year, we announced our support for OpenAPI in the Alma APIs. This support powers our API Console, enables you to leverage the growing number of tools which support Open API, and can be used as a starting point to build client SDKs. In this blog post, we’ll look at how we use our…

Some institutions maintain records in their catalog which are related to a specific geographic location. Records which represent images, manuscripts, or other material which was either composed in or is pertaining to a location is perhaps best displayed on a map. The Primo customization framework allows us to add a widget which shows the relevant…

Alma APIs support XML and JSON for both the request and response payloads. The choice between these formats is left to the preference of the institution or individual programmer. Sometimes the choice of language or platform informs the choice of format, as in the natural fit between Node.js and JSON. Most environments offer tooling which…

Browser security prevents HTTP requests from being made between domains. This "same-origin policy" prevents sensitive information from being revealed to an untrusted party. However, the policy makes it challenging to build JavaScript-based web applications, where AJAX requests are made to a server to retrieve data and display it on the web page. If we want…

Alma recently added support for full text extraction from image files. The resulting text is stored with the file and can be accessed via the file list in the representation resource editor. In addition, the full-text can be searched in the Book Reader viewer. Full-text can be extracted using the “Extract Fulltext” job. In the…

In recent blog posts, we discussed newly-announced support for the OpenAPI standard for Alma APIs. Another benefit of OpenAPI is the ability to generate client class libraries or server stubs for testing. For many developers, “thin” clients for calling REST APIs are sufficient for their needs. A “thin” client encapsulates basic HTTP functionality, such as…

In this blog post, we'll review how to extract text from images in Alma and how that text can be…

Case sensitivity in computer programs determines how fields values are treated. Case-sensitive means that the computer program only matches values with the same case (lower/upper). Case-insensitive means the program ignores case and matches values regardless of their lower or upper case letters, e.g. "My Name" = "my name"). Alma has always treated primary identifiers in…

As we've discussed previously, the Linked Data features in Alma now allow bibliographic records to be retrieved in three different formats- BIBFRAME, RDA/RDF and JSON-LD. In addition, staff users can view records in BIBFRAME directly from the record view: For some linked data experts, these formats may be perfectly readable as-is. But they were intended…

All bibliographic and local authority records managed in Alma are available in various linked data formats. Details on Alma’s linked data features are available in the documentation and this blog post. As this is an emerging area, we are exploring possible use cases that can be served well by linked data. A “classic” use of…
