XML and HR-XML (Extensive Markup language)

XML (Extensible Markup Language) is a standardized data format for structuring, storing, and transporting information between systems. HR-XML (now part of HR Open Standards) is a set of XML schemas specifically designed for HR data exchange : enabling different HR systems (ATS, HRIS, payroll, benefits platforms) to share data in a standardized format. HR-XML defines the structure for resume data, job postings, employment data, and other HR information interchange.

HR technology ecosystem complexity: most organizations use multiple HR systems that must exchange data : ATS sends new hire data to HRIS, HRIS sends payroll data to the payroll processor, benefits systems exchange enrollment data with carriers. Without standardization, each integration requires custom development. XML and HR Open Standards reduce integration complexity, cost, and error rate by defining common data structures that systems can interpret without custom mapping.

HR Open Standards is a nonprofit organization that maintains standardized schemas for HR data exchange. It defines XML-based data formats for: recruiting (job postings, candidate profiles, interview schedules), talent management (competencies, skills, performance data), payroll (employee compensation data), benefits administration (enrollment transactions), workforce data (timekeeping, scheduling), and background checks. Vendors that adopt HR Open Standards reduce implementation time for customer integrations significantly.

Typical XML data flow: an ATS exports a new hire’s profile in HR Open Standards XML format; the HRIS imports that XML, parsing the structured fields to create the employee record automatically; payroll receives an XML payload with compensation and deduction data; the benefits platform receives an XML enrollment file. Each step uses standardized field definitions so receiving systems know how to interpret incoming data without manual mapping. Modern REST APIs using JSON have largely replaced XML in new integrations, but XML remains prevalent in benefits and payroll data exchange.

XML file exchange: HR systems export data files in XML format on a schedule (daily, weekly) : batch processing with potential for data to be out of sync between updates. REST API with JSON: HR systems exchange data in real time through API calls : enabling immediate synchronization when data changes. Modern HR technology increasingly uses APIs for real-time integration while XML file exchange remains common for legacy systems (particularly in benefits and payroll where established standards are XML-based). New HR technology buyers should prefer API-first platforms.

HR-XML defines a standardized format for resume data (‘Resume’ or ‘Candidate’ schema) that enables ATS platforms to parse and exchange resume information consistently. Fields include: personal information, employment history (with standardized date and description formats), education (with standardized degree and institution fields), skills (mapped to standardized skill taxonomies), and certifications. Standardized resume XML enables better data portability when organizations switch ATS vendors and enables more accurate matching algorithms that operate on structured data.
