Annex 2: Mapping standards and schemas to schema.org

The use of structured data described in section 1.6.2 requires a mapping between the relevant elements of some of the metadata standards and schemas described in the Guide to the schema.org standard. We provide here a suggested selection and mapping for the core set of elements (we do not attempt to map all possible elements that are common to our schemas and schema.org).

LSMS has been carried out in Albania in the context of continuing                                monitoring of poverty and the creation of policy evaluation system in the framework of the National Strategy for Development and Integration                            (previously the National Strategy for Economic and Social Development). The first Albania LSMS was conducted in 2002, followed by 2003, 2004,                          2005, 2008 and 2012 surveys. In 2012, 6,671 households participated in the survey.",

1.5 Images

The complete list of elements available in schema.org to document an image object is available at https://schema.org/ImageObject. We only show in the table below a selection of the ones we consder the most relevant and frequently available. Images can be documented either using the IPTC-based schema, or the Dublin Core (DCMI)-based schema.
