Digital preservation is the ongoing work of keeping digital files authentic, understandable, and usable as technology changes. It involves more than storing a backup: organizations need to know what they have, verify that files remain intact, preserve the context needed to interpret them, and plan for formats or software that may become obsolete. A digital […]

Application rationalization is a structured review of the software an organization uses to decide what to keep, improve, replace, combine, or retire. It helps leaders see where systems duplicate capabilities, create avoidable risk, or no longer support business goals. The work starts with a trusted application inventory and ends with decisions that have owners, timelines, […]

Optical mark recognition (OMR) detects whether a person marked a known position on a form, such as filling a multiple-choice bubble or checking a box. OMR software maps scanned images to a form template, evaluates defined mark areas, and returns structured values for scoring or downstream processing. It is useful for repeatable forms with fixed […]

Content moderation is the process of reviewing user-submitted material against a service’s rules and deciding whether to allow, limit, remove, or escalate it. A moderation system can combine automated detection, user reports, human review, and appeal workflows. Its job is not simply to block a list of words; it must apply policy in context while […]

Digital rights management (DRM) is a set of technical and operational controls used to manage access to digital content. A service may encrypt a video, document, or ebook and issue a license that defines which account or device can use it and under what conditions. DRM can help content owners enforce licensing terms, but it […]

Enterprise integration patterns are reusable design approaches for moving information between separate applications. They address recurring problems such as routing a message to the right system, translating data formats, handling slow receivers, and responding to failures. Rather than connecting every pair of systems with custom code, teams can use a small set of patterns to […]

Event sourcing stores changes as an ordered history of business events instead of keeping only the latest state of each record. An order system might record “OrderPlaced,” “ItemAdded,” “PaymentAuthorized,” and “OrderShipped,” then derive the current order from that history. The approach gives teams a durable view of what happened, but it adds design and operational […]

Passkeys let a person sign in with a cryptographic credential instead of typing a reusable password. A passkey is created for a particular website or app, and its private key stays with an authenticator such as a phone, computer, or security key. The application stores the corresponding public key and verifies a signed challenge at […]

OpenTelemetry is a vendor-neutral set of APIs, SDKs, conventions, and tools for generating and exporting telemetry from software. It helps teams describe what applications are doing, then send that data to an observability backend. OpenTelemetry does not replace that backend or automatically explain an incident; it creates a consistent path for collecting traces, metrics, and […]

WebRTC is a set of browser and application technologies for exchanging live audio, video, and data with low delay. It supports use cases such as video calls, screen sharing, remote assistance, and collaborative tools. The key design point is that WebRTC handles media capture and peer connectivity, while your product still needs to coordinate sessions, […]
