How can Informatiom Exchange Package Documantation (IEPD) be used to address specific business needs?
Practitioners and industry organizations are defining “reference” information exchange models for specific business needs to reduce arbitrary variations and promote interoperability at the Information Exchange Package level.
GJXDM and NIEM provide a set of defined data and an object structure for that data. However, the models do not define sets of data for particular business information exchanges.
Without the IEPD, there would be no agreement on which GJXDM or NIEM properties (and extended properties) are used or how they are structured within the IEPD. Given the same set of business data requirements, each implementing organization could develop a different IEP to represent that same set of business data. Even if the IEP from a particular sending organization could be interpreted, it would be expensive for organizations to handle the IEP variations from the different senders.
By developing and reaching agreement on the IEPD for an information exchange within a particular enterprise, participants can send an IEP that can be understood by those receiving the IEP whether it’s within the state, county, or nationally.
If Reference IEPD for an Incident Report is developed and recognized by a nationally respected organization, states are more likely to use that Reference Incident Report IEPD as a model for developing their state-specific Incident Report IEP. This minimizes unnecessary differences from state to state while still enabling each state to tailor the Incident Report IEPD to meet state-specific business needs. It may be that the Reference Incident Report IEPD is inclusive enough that it can be used as-is for a particular state. The state-specific Incident Report IEPD would be used to exchange incident information between different jurisdictions within the state or between a jurisdiction and the state repository.
Carrying this concept further down, a county-wide enterprise could use the state Incident Report IEPD as a reference model to develop the IEPD for an Incident Report meeting the specific business needs of the county. This county-specific Incident Report IEPD would be used to exchange incident information between different organizations within the county.
Continuing with this concept going up, the Reference IEPD for an Incident Report could be used as-is at the national enterprise level for exchanging incident information between states or between states and the federal government.
The benefit of this consistency is that organizations implementing information exchanges can more quickly and cost-effectively deploy them across multiple jurisdictions at all levels. IEPD (and Reference IEPD) takes the benefits of using GJXDM and NIEM to a higher level. Ultimately, organizations implement information exchanges based on IEPD, not on GJXDM or NIEM.
