The value of element premis:premis/premis:object[@xsi:type="premis:file"]/premis:objectCharacteristics/premis:fixity/premis:messageDigestAlgorithm MUST be set to MD5.
The value of attribute premis:premis/premis:object[@xsi:type="premis:file"]/premis:objectCharacteristics/premis:fixity/premis:messageDigestAlgorithm/@valueURI MUST be set to "http://id.loc.gov/vocabulary/preservation/cryptographicHashFunctions/md5".
The csip:CONTENTINFORMATIONTYPE attribute MUST be set to OTHER and the csip:OTHERCONTENTINFORMATIONTYPE attribute MUST be set to https://data.hetarchief.be/id/sip/3.0/basic.
The dc+schema.xml file MUST declare the http://purl.org/dc/terms/ (dcterms), https://schema.org/ (schema), https://data.hetarchief.be/ns/rights/ (haRig), http://www.w3.org/2001/XMLSchema-instance (xsi) and http://id.loc.gov/datatypes/edtf/ (edtf) namespaces in its root element.
The dc+schema.xml file MUST adhere to the restrictions on cardinality of terms outlined in the table below; if a term is not listed with a restriction on cardinality, it MAY be used multiple times.
The dc+schema.xml file MUST contain a shared ID with a PREMIS object in the preservation/premis.xml file, stored in the <dcterms:identifier> element (see next section).
The dc+schema.xml file MUST NOT contain additional IDs besides the shared ID in the <dcterms:identifier>; these MUST be added in the preservation/premis.xml file.
Some descriptive metadata elements of datatype String MUST contain an attribute @xml:lang that indicates the language of the metadata element’s value (in order to, for example, specify a title or description in multiple languages); these are indicated with [@xml:lang=*] in the table below. Other elements MUST NOT contain this attribute.
Rights-related descriptive agents, including rights holders, owners, licence distributors, performers, and producers, remain in dc+schema.xml. Rights statements, reuse conditions, and access policy MUST be recorded in PREMIS at the package level or representation level, as applicable. The deprecated dcterms:rights and dcterms:license elements SHOULD NOT be used for new SIPs.
For elements that require the @xml:lang attribute, it is still necessary to supply an element with @xml:lang set to nl even if there is no Dutch content available (e.g., the original title is in English or French and no translation was ever made, or the title is the same in both languages). In that case, a title in another language can be copied as if it were Dutch.
The root element for descriptive metadata. It MUST declare http://purl.org/dc/terms/ (dcterms), https://schema.org/ (schema), https://data.hetarchief.be/ns/rights/ (haRig), http://www.w3.org/2001/XMLSchema-instance (xsi), http://id.loc.gov/datatypes/edtf/ (edtf), and the default namespace https://data.hetarchief.be/id/sip/3.0/basic.
An unambiguous and unique reference to the Intellectual Entity/Entities present in the SIP.This identifier MUST be used to establish a link between the dc+schema.xml file and the relevant PREMIS object in the preservation/premis.xml file.
The role with which the creator, publisher, contributor, performer, or producer was involved in creating, publishing, contributing to, performing, or producing the digitally reproduced artwork.
Element metadata/(schema:creator|schema:publisher|schema:contributor|schema:performer|schema:producer|schema:copyrightHolder|haRig:broadcastingOrganization|haRig:licenseDistributor|haRig:owner)/schema:name[@xml:lang=*]
Name
Agent name
Description
The name of the thing, person, or organization. The name MAY occur more than once only in different languages. Every name MUST have an xml:lang attribute and, when the agent is present, a Dutch name with xml:lang="nl" MUST be supplied.
A string or text indicating the unit of the weight measurement value, which MUST be set to kg (kilograms). Useful if you cannot provide a standard unit code for schema:unitCode.
The material used to create the physical artwork, e.g. Oil, Watercolour, Acrylic, Linoprint, Marble, Cyanotype, Digital, Lithograph, DryPoint, Intaglio, Pastel, Woodcut, Pencil, Mixed Media, etc.
The dc+schema.xml file at the package-level contains descriptive metadata about the IE(s) of the SIP. It relies on the DCTERMS and SCHEMA metadata schema in order to facilitate a basic description with a limited number of descriptive metadata elements.
There is a link present between each dc+schema.xml file and the PREMIS Intellectual Entity in the preservation/premis.xml file via a shared ID. This shared ID is stored in the <dcterms:identifier> element of each dc+schema.xml file and in a <premis:objectIdentifier> element of each PREMIS object in the preservation/premis.xml file.
Please note that additional IDs must be dealt with in the preservation/premis.xml file via <premis:objectIdentifier> elements in which the type of ID is specified using the <premis:objectIdentifierType> element.
