What Are Open Standards?

Background

The use of open standards can help provide interoperability and maximise access to resources and services. However this raises two questions: "Why open standards?" and "What are open standards?".

Why Open Standards?

Open standards can provide several benefits:

• Application Independence: To ensure that access to resources is not dependent on a single application.
• Platform Independence: To ensure that access to resources is not restricted to particular hardware platforms.
• Long-term Access: To ensure that quality scholarly resources can be preserved and accessed over a long time frame.
• Architectural Integrity: To ensure that the architectural framework for IT developments is robust and can be further developed in the future.

What Are Open Standards?

The term "open standards" is ambiguous. As described in Wikipedia "There is no single definition and interpretations vary with usage" [1]. The EU's definition is [2]:

• The standard is adopted and will be maintained by a not-for-profit organisation, and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties (consensus or majority decision etc.).
• The standard is adopted and will be maintained by a not-for-profit organisation, and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties (consensus or majority decision etc.).
• The intellectual property - i.e. patents possibly present - of (parts of) the standard is made irrevocably available on a royalty-free basis.
• There are no constraints on the re-use of the standard.

Some examples of recognised open standards bodies are given in Table 1.

Other Types Of Standards

The term proprietary refers to formats which are owned by an organisation, group, etc. The term industry standard is often used to refer to a widely used proprietary standard. For example, the proprietary Microsoft Excel format is sometimes referred to as an industry standard for spreadsheets. To make matters even more confusing, the prefix is sometime omitted and MS Excel can be referred to as a standard.

To further confuse matters, companies which own proprietary formats may choose to make the specification freely available. Alternatively third parties may reverse engineer the specification and publish the specification. In addition tools which can view or create proprietary formats may be available on multiple platforms or as open source.

In all these cases, although there may appear to be no obvious barriers to use of the proprietary format, such formats should not be classed as open standards as they have not been approved by a neutral standards body. The organisation owning the format may chose to change the format or the usage conditions at any time. File formats in this category include Microsoft Office formats, Macromedia Flash and Java.
