Article

An article represents a piece of content created in the content management system. Different types of content like text or video articles share the same message structure, they can be distinguished by the Article.Type field. Text articles (type = Article.Type.ARTICLE) also have Article.SubType to differentiate its purpose and form.

Teaser

To improve performance of database access and during network transmission tapir is using a lightweight representation of Article in some places.

Depending on the service used to retrieve an article, the Article message might only contain data required on section pages:

• Article.body set to null
• Article.elements filtered by Element.relations to only contain TEASER, but neither OPENER nor SOCIAL

Thus, not containing any data that is only required on detail pages. This lightweight representation is sometimes referred to as Teaser.

message Article {
int64 id = 1;
Type type = 2;
SubType sub_type = 3;
stroeer.core.v1.Reference section_tree = 4;
map<string, string> fields = 5;
repeated Body bodies = 6;
Metadata metadata = 7;
repeated Element elements = 8;
repeated Keyword keywords = 9;
repeated int64 onwards = 10 [deprecated = true];
map<string, Article> variants = 11;
repeated Author authors = 12;
repeated Article related_articles = 13;
repeated string entities = 100 [deprecated = true];

[~]

fields

The entry set is defined by the content management system and will vary depending on the main type of the article.

⚠ Clients must be resilient to unknown or missing entries. ⚠

For Article.Type.ARTICLE

this map will contain the following data:

For Article.Type.GALLERY

this map will contain the following data:

enum Type

enum Type {
TYPE_UNSPECIFIED = 0;
ARTICLE = 1;
IMAGE = 2 [deprecated = true];
VIDEO = 3;
GALLERY = 4;
EMBED = 5;
AUTHOR = 6;
AGENCY = 7 [deprecated = true];
EXTERNAL = 8;
INTERNAL = 100;
}

enum SubType

Content with Type.ARTICLE is usually sub typed to alter its form and purpose.

enum SubType {
SUB_TYPE_UNSPECIFIED = 0;
NEWS = 1;
COLUMN = 2;
COMMENTARY = 3;
INTERVIEW = 4;
CONTROVERSY = 5;

Article ۰ Body

The Body represents a basic block. Each Body is self-contained and holds all the data required for rendering within its data structures.

Common use cases for this are Type.BODY where the textual article body can be found and the TYPE.ARTICLE_SOURCE where onward articles are referenced.

message Body {
repeated BodyNode children = 1;
Type type = 2;

[~]

Type

Each Body has a Body.Type to help the consumer to correctly interpret the BodyNode's content.

enum Type {
TYPE_UNSPECIFIED = 0;
BODY = 1;
ARTICLE_SOURCES = 2;
DISCLAIMER = 3;
TRUST_BOX = 4;
TABLE_OF_CONTENTS = 5;
}

[~]

BodyNode

Recursive structure representing all types of possible nodes inside an article.

One use-case is to represent HTML-like markup in tapir, but it is also used to map custom elements that require a strict positional placement within the textual body. Things that are not part of the textual article body are represented as individual Body parts so they can be rendered independently if required.

Clients must be resilient to unknown or missing nodes.

message BodyNode {
string type = 1;
string text = 2;
map<string, string> fields = 3;
repeated BodyNode children = 4;
repeated Element elements = 5;

Article ۰ Element

Elements are self-contained objects that represent structured data that is usually too complex to fit into our usual workhorse which is the Body.

Elements can appear in multiple places within the Article:

1. Article.elements

Elements of the article which are not part of the textual body, e.g. author, opener and teaser. Those elements should be used to render the article as a teaser e.g. on section pages.

2. BodyNode.children:

Is the place where Element are quite commonly used. They come in various types and will be rendered inplace, thus breaking up the textual body.

3. Elements.children:

Some more sophisticated Elements make use of nesting to make their API representation more concise and help to structure things hierarchically:

• video uses nesting to model its optional poster image which itself is a normal image.

• galleries have their individual images nested within.

Different types of elements like images or videos share the same message structure distinguished by the ElementType field.

See Sample section.

message Element {
Type type = 1;
repeated Relation relations = 2;

repeated Element children = 4;

enum State

State of the item (Article, Element) in the content management system. The state in combination with start_time and end_time determines whether or not this item should be rendered; this must be respected by all consumers especially when content is duplicated or cached.

The terms deleted (articles) and archived (media lib) are interchangeable/synonyms. This enum combines those two into State.DELETED. An Article is in State.DELETED if it was deleted in the content management system, or if it's end_time has been reached.

An Article is in State.DRAFT if it has never been published, or if the start_time lies in the future.

⚙︎ CoreArticleService

Core service to either query a single article (rpc GetArticle()) identified by its id or to query multiple articles (rpc ListArticles()) by providing a query.

All results returned from this service are unfiltered by default, hence they may contain elements that are expired, not yet valid or whose state is not PUBLISHED. This behaviour can be changed by providing a RequestSettings object.

service ArticleService {
rpc GetArticle(GetArticleRequest) returns (stroeer.core.v1.Article) {}
rpc BatchGetArticles(BatchGetArticlesRequest) returns (BatchGetArticlesResponse) {}
rpc ListArticles(ListArticlesRequest) returns (ListArticlesResponse) {}
// Allow Empty as request param
// buf:lint:ignore RPC_REQUEST_STANDARD_NAME
rpc ListSections(google.protobuf.Empty) returns (ListSectionsResponse) {}
}

[~]

⚙︎ GetArticle

rpc GetArticle (GetArticleRequest) returns (stroeer.core.v1.Article) {}

returns a single stroeer.core.v1.Article if the given id exists, an Error, otherwise. (todo: describe errors)

message GetArticleRequest {
int64 id = 1;
RequestSettings request_settings = 2;
}

[~]

⚙︎ BatchGetArticle

returns multiple stroeer.core.v1.Article for the given ids. The ordering of items will the same ordering as the ids requested. If an id does not exists, it is omitted in the result (no error will be raised).

There is a maximum of 100 items that can be queried in one batch.

message BatchGetArticlesRequest {
repeated int64 ids = 1;
RequestSettings request_settings = 2;
}

[~]

returns a message-listarticlesresponse with articles matching the query. If the results exceed 100 Articles or 1 MB the response can be paginated to obtain additional results.

ListArticlesRequest

message ListArticlesRequest {
Query query = 1;
Filters filters = 2;

string page_token = 4;
RequestSettings request_settings = 5;

Query

Specify the search criteria. The list-API is build around sections which come in two flavors:

1. home_section: find all articles that resides within that exact section. The home_section is equal to the settings found in the CMS, e.g. /nachrichten/wissen/
2. root_section: this property is derived from the home_section path by retaining only the root folder, e.g. for /nachrichten/wissen/ the root_section becomes /nachrichten/

In most cases using the root_section should yield better results since it will also find content in nested sections whereas home_section would only return content which was curated into the exact section that was queried.

message Query {
string path = 1;

Filters

If you need to further refine the Query results, you can optionally provide a filter expression. A filter expression determines which items within the Query results should be returned to you. All of the other results are discarded.

A filter expression is applied after a Query finishes, but before the results are returned. Therefore, a Query consumes the same amount of read capacity, regardless of whether a filter expression is present.

message Filters {
repeated Article.Type type_includes = 1;
repeated Article.Type type_excludes = 2;
repeated Article.SubType sub_type_includes = 3;
repeated Article.SubType sub_type_excludes = 4;
}

This services allows to query curations within the CMS. In the CMS domain this is implemented as Lists which usually contain one ore more Articles.

service CurationService {
rpc GetCuration(GetCurationRequest) returns (GetCurationResponse) {}
rpc BatchGetCuration(BatchGetCurationRequest) returns (BatchGetCurationResponse) {}
}
