7.7  Getting started with XML Indexing
The XML indexer enables the high-volume archiving of XML data in a scalable and extensible 
manner. 
The XML indexer was developed to support the growing need to efficiently and effectively 
store large quantities of XML data, for example:
/SM590000The European Union’s implementation of a Single Euro Payments Area (SEPA). SEPA 
replaced the existing domestic retail credit transfers and direct debits with standardized 
European payments that are based on Extensible Markup Language (XML) International 
Organization for Standardization (ISO) 20022 messages. ISO 20022 provides a more 
efficient way of developing and implementing messaging standards that financial 
institutions and clients use to exchange massive amounts of transactional information. 
/SM590000Other XML standards exist and continued to be developed, such as ACORD (Insurance 
industry), AgXML (Agriculture), and Health Level Seven (Health industry). 
/SM590000XML document formats were developed, such as Office Open XML (OOXML) and Open 
Document (OASIS).
With XML indexing, you can automatically batch index and archive XML transactional 
messages and statements into the Content Manager OnDemand repository. Documents are 
identified and extracted during indexing. Resources are extracted, and, together with the 
data, compressed and archived. Multiple stylesheets can be specified to meet device and 
accessibility requirements. 
XML steeliest (resource) archiving is critical. Content Manager OnDemand optimizes the 
storage of XML data by storing only a single version of a resource and then associating it with 
all of the archived documents. Document resources can be automatically collected and 
managed.
