Simple Publishing Interface
This European Standard specifies the Simple Publishing Interface (SPI), an abstract protocol for publishing digital content and/or the metadata that describes it into repositories in a way that preserves the references between the two. This protocol is designed to facilitate the transfer of learning materials from tools that produce learning materials to applications that manage learning objects and metadata. It is also applicable to the publication of a wider range of digital objects.
The objectives behind SPI are to develop practical approaches towards interoperability between repositories for learning and applications that produce or consume educational materials. Examples of repositories for learning include educational brokers, knowledge pools, institutional repositories, streaming video servers, etc. Examples of applications that produce these educational materials are query and indexation tools, authoring tools, presentation programs, content packagers, etc.
Whilst the development of the SPI specification draws exclusively on examples from the education sector, it is recognised that the underlying requirement to publish content and metadata into repositories crosses multiple application domains.
This abstract model has been designed to be implemented using existing specifications such as v1.3 Simple Web-service Offering Repository Deposit (SWORD) profile [SWORD], Package Exchange Notification Services [PENS] and the publishing specification that was developed in the ProLearn Network of Excellence [PROLEARN SPI]. The intent of this work is thus not to create yet another specification but to create a model that can be bound to existing technologies in order to make sure that these technologies are used in a way that takes into account requirements specific to the learning domain, where it is necessary to publish both content and metadata that references it in a way that preserves these references.
The SPI model enumerates the different messages that are interchanged when publishing metadata and content.

Interface de publication simple
La présente Norme européenne spécifie l'interface de publication simple (SPI), un protocole abstrait de publication de contenu numérique et/ou de métadonnées qui le décrivent, dans des entrepôts de données, en préservant les références qui les relient. Ce protocole est conçu pour faciliter le transfert de documents pédagogiques depuis des outils qui produisent des documents pédagogiques vers des applications qui gèrent des objets et des métadonnées pédagogiques. Il permet également de publier une plus large gamme d'objets numériques.
L'interface SPI a pour objectifs de développer des approches concrètes garantissant l'interopérabilité entre des entrepôts de données pédagogiques et des applications qui produisent ou utilisent des documents éducatifs. Parmi les exemples d'entrepôts de données figurent les courtiers en enseignement, les viviers de connaissances, les entrepôts de données institutionnels, les serveurs de diffusion de vidéos, etc. Les applications qui produisent ces documents éducatifs sont, par exemple, des outils de requête et d'indexation, des outils de création, des programmes de présentation, des systèmes de paquetages de contenus, etc.
Bien que la spécification de l'interface SPI ait été élaborée en s'appuyant uniquement sur des exemples issus du secteur de l'éducation, il est évident que l'exigence sous-jacente concernant la publication de contenus et de métadonnées dans des entrepôts de données s'applique à d'autres domaines.
Ce modèle abstrait a été conçu pour être mis en oeuvre à l'aide de spécifications existantes, telles que le profil [SWORD] (Simple Web-service Offering Repository Deposit) v1.3, [PENS] (Package Exchange Notification Services) et la spécification de publication développée dans le réseau d'excellence ProLearn [PROLEARN SPI]. Par conséquent, l'objectif de ce travail n'est pas de créer une spécification de plus, mais de créer un modèle pouvant être relié aux technologies existantes, de façon à garantir que l'utilisation de ces technologies tiendra compte des exigences spécifiques au domaine de l'apprentissage, dans lequel il est nécessaire de publier à la fois des contenus et des métadonnées qui le référencent tout en préservant ces références.
Le modèle d'interface SPI énumère les différents messages qui sont échangés lors de la publication de métadonnées et de contenus.
Vmesnik za enostavno objavljanje
Standard EN 16425 opisuje vmesnik za enostavno objavljanje (SPI), abstrakten protokol za objavljanje digitalne vsebine in/ali metapodatkov, ki to vsebino opisujejo, v shrambo na način, ki ohranja sklicevanja med obema. Ta protokol je namenjen lajšanju prenosa učnega gradiva iz orodij, ki proizvajajo učna gradiva, v aplikacije, ki upravljajo učne objekte in metapodatke. Uporablja se tudi za objavljanje širšega razpona digitalnih objektov. Cilj modela SPI je razvoj praktičnih pristopov k interoperabilnosti med shrambami za učenje in aplikacijami, ki proizvajajo ali izkoriščajo izobraževalno gradivo. Med primere shramb za učenje spadajo izobraževalni posredniki, bazeni znanja, institucionalne shrambe, strežniki s pretočnim prenosom videogradiva itd. Med primere aplikacij, ki proizvajajo ta izobraževalna gradiva, spadajo orodja za poizvedbo in indeksacijo, avtorska orodja, predstavitveni programi, oblikovalci vsebine itd. Medtem ko razvoj specifikacije SPI temelji izključno na primerih iz izobraževalnega sektorja, se priznava, da osnovna zahteva za objavo vsebin in metapodatkov v shrambe prečka več domen aplikacij. Ta abstraktni model je bil zasnovan za izvajanje z uporabo obstoječih specifikacij, kot je profil Simple Web-service Offering Repository Deposit (SWORD) v1.3 [SWORD], Package Exchange Notification Services [PENS] in specifikacija za objavljanje, ki je bila razvita v omrežju ProLearn Network of Excellence [PROLEARN SPI]. Namen tega dokumenta torej ni ustvariti še ene specifikacije, ampak izdelati model, ki ga je mogoče uporabljati z obstoječimi tehnologijami, da bi pri uporabi teh tehnologij upoštevali zahteve, specifične za učno domeno, kadar je potrebno objaviti vsebino in metapodatke s takim sklicevanjem, ki ohranja ta sklicevanja. Model SPI oštevilčuje različna sporočila, ki se izmenjavajo pri objavi metapodatkov in vsebine.

Figure 1 — Example SPI architectures SPI also enables flexible architectures where a middleware component gathers learning resources or metadata through an SPI interface (from authoring tools or harvesters), applies value adding operations on these, and then stores them into a backend repository. Examples of such operations are disaggregation of material into small reusable components, automatic generation of metadata and validation or translation services.
Figure 2 — AloCom architecture Such architecture has been implemented in the context of the AloCom project (Figure 2). [ALOCOM]. This architecture contains a plug-in for MS PowerPoint, a source that can publish to a middle layer application, which is the target of this publishing operation. Next, the AloCom middleware disaggregates the material into small reusable components such as diagrams, individual slides, etc. and automatically generates metadata for each component. Each individual component is then published by the middleware component into a specialised AloCom repository where individual components are available for reuse. The AloCom middleware acts as a source and the AloCom repository as target. Interoperability in both publishing steps is important. First, as several applications (not only
