Reference excerpt

The Schools Interoperability Framework, Systems Interoperability Framework (UK), or SIF, is a data-sharing open specification for academic institutions from kindergarten through workforce. This specification is being used primarily in the United States, Canada, the UK, Australia, and New Zealand; however, it is increasingly being implemented in India, and elsewhere. The specification comprises two parts: an XML specification for modeling educational data which is specific to the educational locale (such as North America, Australia or the UK), and a service-oriented architecture (SOA) based on both direct and brokered RESTful-models for sharing that data between institutions, which is international and shared between the locales. SIF is not a product, but an industry initiative that enables diverse applications to interact and share data. As of March 2007, SIF was estimated to have been used in more than 48 US states and 6 countries, supporting five million students. The specification was started and maintained by its specification body, the Schools Interoperability Framework Association, renamed the Access For Learning Community (A4L) in 2015.

History Traditionally, the standalone applications used by public school districts have the limitation of data isolation; that is, it is difficult to access and share their data. This often results in redundant data entry, data integrity problems, and inefficient or incomplete reporting. In such cases, a student's information can appear in multiple places but may not be identical, for example, or decision makers may be working with incomplete or inaccurate information. Many district and site technology coordinators also experience an increase in technical support problems from maintaining numerous proprietary systems. SIF was created to solve these issues. The Schools Interoperability Framework (SIF) began as an initiative chiefly championed initially by Microsoft to create "a blueprint for educational software interoperability and data access." It was designed to be an initiative drawing upon the strengths of the leading vendors in the K-12 market to enable schools' IT professionals to build, manage and upgrade their systems. It was endorsed by close to 20 leading K-12 vendors of student information, library, transportation, food service applications and more. The first pilot sites began in the summer of 1999, and the first SIF-based products began to show up in 2000. In the beginning it was not clear which approach would become the national standard in the United States. Both SIF and EDI were vying for the position in 2000 but SIF began taking the lead in 2002 or so. In 2000, the National School Boards Association held a panel discussion during its annual meeting on the topic of SIF. In 2007 in the United Kingdom Becta has championed the adoption of SIF as a national standard for schools data interchange. In 2008 it was announced that in the UK the standard will become known as the "Systems Interoperability Framework". This reflects the intention in the UK to develop SIF to be used in other organizations beyond just schools.

Members The SIF specification is supported by the A4L community. A4L members collaborate on a variety of technical solutions and standards which include but are not limited to the Schools Interoperability Framework. Members include districts, states, vendors, non-profits, and various government agencies.

Criticism SIF has all the pains and challenges that come with any SOA specification and data model. When building specifications via consensus not everyone is always happy and sometimes the end product isn't perfect. Also given all the moving parts in modeling the entire K12's enterprise the specification has many points of possible failure. This is not particular to SIF but to any record-level, automated system moving standardized data from one source to another in a heterogeneous environment. Out-of-the-box interoperability and ease of use and implementation were part of a 12-18 month focus from 2007 and through 2009.

How SIF Works SIF 2.x relied on using a broker called a Zone Integration Server (ZIS) to manage communication between applications. SIF 3.x and SIF 2.8+ allows for both brokered and direct communication between applications.

Brokered Rather than have each application vendor try to set up a separate connection to every other application, SIF has defined the set of rules and definitions to share data within a "SIF Zone"— or Environment which is a logical grouping of applications in which software application agents communicate with each other through a central communication point. Zones are managed by an enterprise data broker sometimes called a Zone Integration Server (ZIS). A single ZIS can manage multiple Zones. However, the current infrastructure specification supports RESTful connections directly between applications AND/OR utilizing a brokered environment. Data travels between applications as a series of standardized messages, queries, and events written in XML or JSON and sent using Internet protocols. The SIF specification defines such events and the "choreography" that allows data to move back and forth between the applications.

Direct Direct SIF allow one application to communicate directly to another via simple REST calls to PUT, POST, GET, or DELETE resources. This is ideal for simple environments with two or maybe three players where complex choreographies are not necessary. It is easier to implement than a brokered environment in two- or three-node situations.

Interface Code SIF Agents are pieces of software that exist either internal to an application or installed next to it. The SIF Agents function as extensions of each application and serve as the intermediary between the software application and the SIF Zone. In brokered environments, the broker keeps track of the Agents registered in the environment and its Zones and manages transactions between Agents, enabling them to provide data and respond to requests. The broker controls all access, routing, and security within the system. Standardization of the behavior of the Agents and the broker means that SIF can add standard functionality to a Zone by simply adding SIF-enabled applications over time.

Worked examples

Example 1 — a first encounter with Schools Interoperability Framework

Start with the simplest possible case. Write down what Schools Interoperability Framework claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Schools Interoperability Framework before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Schools Interoperability Framework ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Schools Interoperability Framework

In research: Schools Interoperability Framework appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Schools Interoperability Framework in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Schools Interoperability Framework is common in secondary-school and first-year university syllabi. It links to neighbouring topics Educational technology standards, Interoperability, so understanding it makes those chapters shorter.
In everyday life: Look for Schools Interoperability Framework outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
