The Metadata Lifecycle
| Introduction |
|---|
Metadata has always been defined as the "data about the data", however the industry has yet to understand how to effectively collect, manage and use that metadata. The picture below provides a high level concept of how metadata can be used. The question is how to actually put this picture into practice. In August PHUSE hosted a Single Day Event in Philadelphia followed by a Metadata Discussion Club at the Annual Conference. This Advance Hub page provides a summary and the beginning of the ongoing discussions around the definition and use of metadata. |

The well-thought, planned process will yield more complete metadata, but in most of cases, metadata will be modified during the process and will be completed almost at the same time, more accuratley just before all the analyses and datasets are finished. |
| Definition of Metadata |
|---|
Section content first added by: Chris Decker At the PHUSE annual conference, an engaging discussion was held with the initial goal of defining the the definition of metadata. At the end of this discussion the group came up with the following definition. Metadata is a collection of information that puts data into context. Ot Other comments were made to help clarify the definition.
Additionally, the purpose of collecting metadata must be driven by the needs of the business. (Examples to be added). Do you agree? |

Section content first added by: Chris Decker Within the definition of metadata, the word context was used. Now we must define the different aspects of context that will help better define concrete needs of metadata. Aspects of Context:
