# vi. Interoperability & Systems Integration

Interoperability and systems integration enable asset data to move between platforms, stakeholders, and workflows without losing meaning or reliability. These capabilities reduce fragmentation, support scale, and allow information to remain usable across the real estate lifecycle.

#### **API (Application Programming Interface)**

A defined interface that allows software systems to exchange data in a controlled and structured manner.

#### **Data Mapping**

The process of aligning data fields between different systems or schemas.

#### **Integration Layer**

The technical layer that manages data exchange and coordination between systems.

#### **Interoperability**

The ability of different systems to exchange data and interpret it consistently.

#### **Schema Alignment**

The harmonization of data structures to enable compatibility across platforms.

#### **Semantic Consistency**

The preservation of meaning when data is transferred between systems.

#### **System Integration**

The linking of software platforms to enable shared data and workflows.

#### **Vendor Lock-In**

Dependence on a single system that limits data portability or system flexibility.

#### **Version Compatibility**

The ability of systems to exchange data despite differences in versions or updates.
