INSPIRE Metadata TG v2 Guide national Notes
"TG Requirement C.1: metadata/2.0/req/common/xml-schema -> INSPIRE metadata records shall be encoded in XML format valid against one of the following XML Schemas: - [CSW2 AP ISO] XML Schema13, - [ISO 19139] XML Schema as available in the ISO repository14, or - [ISO 19139] XML Schema as available in the OGC schema repository15. All three of these XML Schemas declare the same namespace http://www.isotc211.org/2005/gmd. The metadata identification info property for INSPIRE Spatial Data Services shall be encoded using the service metadata XML Schema available in the OGC schema repository. This schema is an XML implementation of the [ISO 19119] service metadata, and it declares the namespace http://www.isotc211.org/2005/srv." Exigence XX
"TG Requirement C.2: metadata/2.0/req/common/root-element
The metadata for an INSPIRE data set, data set series or service shall be encoded using exactly one gmd:MD_Metadata element as specified in the XML Schema rules and in the TG Requirements of the Conformance Classes in this specification. Additionally the requirements of [ISO 19139], [ISO 19115] and [ISO 19119] shall be followed for describing the metadata records in cases where neither the XML Schemas nor the TG Requirements in this specification require otherwise."
"TG Requirement C.3: metadata/2.0/req/common/code-list-value
The code list value shall be encoded using the codeListValue attribute of the relevant ISO 19139 element. The value shall be the identifier of the code list value, as defined in the name column of the tables in [ISO 19115], Annex B."
"TG Requirement C.4: metadata/2.0/req/common/free-text
Free text elements of type gco:CharacterString_PropertyType in INSPIRE metadata shall be expressed in one of the following ways: 1. using the gco:CharacterString child element, 2. using gmx:Anchor child element, or 3. re-typing the containing element to gmd:PT_FreeText_PropertyType using the xsi:type attribute and providing both gco:CharacterString and gmd:PT_FreeText child elements. For options 1 and 2 the character string content of elements shall be provided in the language of the metadata. For option 3 the definition of the used locale shall be provided either using an URI pointing to a gmd:MD_Metadata/gmd:locale element within the same document or to an externally provided gmd:PT_Locale element. The character string content shall not be empty unless explicitly allowed in the element specific TG Requirements."
"TG Requirement 1.2: metadata/2.0/req/datasets-and-series/only-one-md-data-identification
The first gmd:identificationInfo property of gmd:MD_Metadata element shall contain only one gmd:MD_DataIdentification element for identifying the described INSPIRE data set or data set series."
"TG Recommendation 1.1: metadata/2.0/rec/datasets-and-series/md-element-id
The gmd:MD_DataIdentification elements should contain a unique identifier of the element itself to be used for referring from within the Spatial Data Service metadata records to indicate a coupled resource. This identifier should be provided as the value of attribute id of gmd:MD_DataIdentification element. This identifier should be persistent for a particular data set or service, and unique within the all the id elements of the metadata record document and other XML documents it may appear in (like GetRecords responses of Discovery Service). The persistence of the id attributes is important to prevent breaking the coupled resource links between the service metadata and the data set metadata.
NOTE A unique identifier of the gmd:MD_DataIdentification element is not necessary when building the coupled resource link by providing a Unique Resource Identifier that is resolved to a URL containing an abstract pointer to the gmd:MD_DataIdentification element (see section 4.1.2.4)."
"TG Requirement C.8: metadata/2.0/req/common/resource-title
A human readable, non-empty title of the described data set, data set series or service shall be provided. It shall be encoded using the gmd:citation/gmd:CI_Citation/gmd:title element with a Non-empty Free Text Element content in the language of the metadata. The multiplicity of the element is 1." EXIGENCE INSPIRE E1 :
● L’intitulé (ou le titre) de la ressource doit être un nom caractéristique et souvent unique sous lequel la ressource est connue.
● Cet élément est une chaîne de caractères obligatoire (texte libre) et ne peut pas être répété.
"TG Recommendation C.3: metadata/2.0/rec/common/resource-title
The Resource title should be concise and clearly understandable. It should not contain unexplained acronyms or abbreviations. It is recommended a maximum length of 250 characters and keeping the similarity with the original title of the resource, in the sense of the ‘official naming’.
If the data or service is part of a larger project, it is recommended to indicate the Project at the end of the title, in brackets. In case of Project names, abbreviations are allowed, as long as the rest of the title follows the guidelines above and the abbreviation is spelled out immediately in the abstract."

"TG Requirement C.9: metadata/2.0/req/common/resource-abstract A non-empty brief narrative summary of the content of the described data set, data set series or service shall be provided. It shall be encoded using the gmd:abstract element with a Non-empty Free Text Element content in the language of the metadata. The multiplicity of this element is 1." "TG Recommendation C.4: metadata/2.0/rec/common/resource-abstract The resource abstract is a succinct description that can include: - A brief summary with the most important details that summarise the data or service - Coverage: linguistic transcriptions of the extent or location in addition to the bounding box - Main attributes - Data sources - Legal references - Importance of the work The most important details of the description should be summarised in the first sentence or the first 256 characters. Unexplained acronyms should not be used."

"TG Requirement 1.1: metadata/2.0/req/datasets-and-series/resource-type The resource type shall be declared as ""dataset"" or ""series"" using the first gmd:hierarchyLevel child element of gmd:MD_Metadata. The gmd:hierarchyLevel shall contain a gmd:MD_ScopeCode element."

If no online access for the data set or data set series is available, but there is a publicly available online resource providing additional information about the described data set or data set series, the URL pointing to this resource shall be given instead. These links shall be encoded using gmd:transferOptions/gmd:MD_DigitalTransferOptions/gmd:onLine/gmd:CI_OnlineResource/gmd: linkage/gmd:URL element. The multiplicity of this element is 0..n." "A Resource Locator encoded using the gmd:CI_OnlineResource element may also include gmd:name, gmd:description, and gmd:function properties. TG Recommendation 1.8: metadata/2.0/rec/datasets-and-series/resource-locator-additional-info The gmd:name, gmd:description, and gmd:function/gmd:CI_OnLineFunctionCode child elements of gmd:CI_OnlineResource element containing the given gmd:linkage element should also be provided, if possible, to give additional information about the provided URL link. The gmd:name and the gmd:description elements should contain Non-empty Free Text Elements. If provided, the gmd:CI_OnLineFunctionCode element should point to one of the values of the ISO 19139 code list CI_OnLineFunctionCode." "TG Recommendation 1.9: metadata/2.0/rec/datasets-and-series/resource-locator-url The URL provided as the value of the gmd:transferOptions/gmd:MD_DigitalTransferOptions/gmd:onLine/gmd:CI_OnlineResource/gmd: linkage/gmd:URL element should point to one of following type of resources: - direct access for downloading the described data set, - a service metadata (capabilities) document of a Spatial Data Service used for providing this data set, - a service WSDL document of a Spatial Data Service used for providing this data set (if SOAP binding is available), - a client application that directly accesses the described data set, or - a web page with further instructions for accessing the described data set."

"TG Requirement 1.3: metadata/2.0/req/datasets-and-series/dataset-uid A unique identifier shall be given for each described dataset or data sets series. This identifier shall be a URI consisting of a namespace uniquely identifying a naming context governed by an identifier authority, and a code unique within this namespace. The identifying URI shall be encoded using gmd:citation/gmd:CI_Citation/gmd:identifier//gmd:code element with a Non-empty Free Text Element content. The multiplicity of this element is 1..." "NOTE The [ISO 19139] xml schemas allow the use of either the MD_Identifier type or its sub-type RS_Identifier, which, in addition to the mandatory code property, also contains an optional codeSpace property. Since many applications only consider the code attribute and semantically RS_Identifier is intended as an ""identifier (…) for reference systems"" [ISO 19115], the MD_Identifier type should be used wherever possible and the complete URI should be encoded in the code element. This also facilitates the implementation of data-service-coupling based on the unique resource identifier (see also 4.1.2.4). TG Recommendation 1.1: metadata/2.0/rec/datasets-and-series/use_md_identifier It is strongly recommended to use the MD_Identifier instead of the the RS_Identifier type and to encode the complete URI in the code element." "TG Recommendation 1.2: metadata/2.0/rec/datasets-and-series/resolvable-uid It is recommended to make the unique resource identifier resolvable into a document providing information about described data set or data sets series. In the case of HTTP URIs34, the public DNS and the usual HTTP URI resolving mechanisms should be used for implementing this resolvability. For other types of URIs, a resolving service should be provided implementing similar functionality. This document retrieved as the result of the resolving process may be, but is not required to be, the metadata description of the described resource. It is also recommended that viewing of the provided document does not require user authentication, authorisation or specialised viewing tools beyond a typical web browser. TG Recommendation 1.3: metadata/2.0/rec/datasets-and-series/persistent-uid The providers of unique resource identifiers should take great care in ensuring that the issued identifiers remain valid and available for the entire availability period of the identified resource, and preferably also after the data set or the data set series has been made unavailable. If a published unique identifier for a resource must be changed during the availability time of the resource, both the old and the new identifier should resolve to the same document described in TG Recommendation 1.2. If this is not possible, the old identifier should resolve to document providing information about the change in the unique identifier and provide the new unique identifier of the described resource. Assigning a published unique resource identifier to another or an extensively restructured data set or data set series should be avoided. Instead a new unique resource identifier should be assigned to the data set in these cases. The persistence and process of preventing breaking the identifier resolvability is crucial for keeping the links between the services and the provided data sets functional."

References to these CI_Citation fragment documents may be used to encode the specification element by reference, using the xlink:href attribute of the gmd:thesaurusName element (see Example 2.10). NOTE 1 The pre-defined CI_Citation elements will be designed to fulfil TG requirement C.15 and will be made available in different languages. The appropriate language version of the CI_Citation element can be accessed using content negotiation (using the Accept-Language HTTP header). NOTE 2 In order to ensure compatibility with all clients (including those that cannot resolve xlinks), the gmd:thesaurusName can also contain the CI_Citation fragment (see Example 2.11Example 2.19). In this case, according to [ISO 19136], ""if both a link and content are present in an instance of a property element, then the object found by traversing the xlink:href link shall be the normative value of the property. The object included as content shall be used by the data recipient only if the remote instance cannot be resolved; this may be considered to be a ""cached"" version of the object."" The use of gmx:Anchor elements and pre-defined XML fragments for CI_Citations will help avoid issues with spelling errors or similar mistakes when providing the thesaurusName elements. They will also allow the unique identification of controlled vocabularies in the metadata. /"

"In the Tables 1 and 2 of [Regulation 1205/2008], Part C, the multiplicity of this element is one or more for both data sets and services. The Article 13 of the [INSPIRE Directive] contains a list of cases where limitations to public access can be set. Concerning providing the metadata for the data sets and services through Discovery services, the limitations on public access can be set on the base of reasons of international relations, public security or national defence. Concerning providing View, Download or Transformation Services, or e-commerce services referred to in Article 14(3) of [INSPIRE Directive], limitations on public access can be set on the base of the following reasons ([INSPIRE Directive], Article 13): (a) the confidentiality of the proceedings of public authorities, where such confidentiality is provided for by law; (b) international relations, public security or national defence; (c) the course of justice, the ability of any person to receive a fair trial or the ability of a public authority to conduct an enquiry of a criminal or disciplinary nature; (d) the confidentiality of commercial or industrial information, where such confidentiality is provided for by national or Community law to protect a legitimate economic interest, including the public interest in maintaining statistical confidentiality and tax secrecy; (e) intellectual property rights; (f) the confidentiality of personal data and/or files relating to a natural person where that person has not consented to the disclosure of the information to the public, where such confidentiality is provided for by national or Community law; (g) the interests or protection of any person who supplied the information requested on a voluntary basis without being under, or capable of being put under, a legal obligation to do so, unless that person has consented to the release of the information concerned; (h) the protection of the environment to which such information relates, such as the location of rare species. ISO 19115 provides a general mechanism for documenting different categories of constraints applicable to the resource (or its metadata). In ISO 19139 XML Schema this mechanism is supported by the element gmd:MD_Constraints and its specifications: • gmd:MD_LegalConstraints for legal constraints; • gmd:MD_SecurityConstraints for security constraints. Since gmd:MD_SecurityConstraints has for many countries only military use, only the element gmd:MD_LegalConstraints is used for this information in the context of this specification. To make the references to the allowed reasons in Article 13 for limiting public access explicit, an INSPIRE code list (Annex D.1 “Limitations on public access) with all the reason values is used in gmd:otherConstraints elements. However, because the domain of the gmd:otherConstraints is a character string (free text), the references to the code list values are done using gmx:Anchor and its xlink:href attribute with the URL pointing to the specified code list value in the INSPIRE Registry."
