Hi everyone, We are thinking to adopt EAD 3.0 schema to map with the descriptive metadata in our self developed catalogue system for ingestion into the digital repository. Our ingestion structure will be mainly TIFF files in a single folder for an item level and an access copy (in PDF format) illustrated in the diagram below. To start with scratches by mapping the EAD 3.0 with ISAD(G) fields in our catalogue system and produced the required metadata in XML for ingestion, are they any advices or tools recommended for us to start with. Your suggestion would be highly appreciated. Thank you. With thanks, Athena WONG Assistant Curator (Digital Archive) Government Records Service, Hong Kong
