How do I edit the granular policies on a materialized Restricted View (RV) of an OSv2 object type?¶

To edit the granular policies on a materialized Restricted View (RV) of an OSv2 object type, you must edit the policies on the RV backing the object type, which will then propagate to the materialized RV.

Is it possible to attach multiple unstructured files to an object by populating a property with an array of RIDs?¶

No, it is not possible to attach files in that manner. You need to explicitly parent the attachment through an action.

Will moving columns between two Restricted Views in a MDO object change the property's API name and RID?¶

The identifiers will remain the same when moving columns between Restricted Views, so the property API name and property rid will not change.

In a scenario where the "Apply most recent value" strategy is selected as the edit conflict resolution, if a user edits a field that was previously `null`, and the pipeline runs but the field remains `null` in the pipeline, what will be shown for the property?¶

When the pipeline runs, if the timestamp property updates to a more recent timestamp than the edit, the property will revert to null. If the timestamp property remains the same (or is null), then the user's edit will win.

How can I map `true` or `false` to "Yes" or "No" in an action form without converting the property to a string?¶

This can be achieved through the Constraints section of the Boolean property configuration by selecting Multiple choice and Define options manually, then setting different display values for true and false.

If a new object is created through an Action and it is backed by a Restricted View, will it be visible to all? Will specifying a value in a certain column restrict access according to that column?¶

Yes, the visibility of the object is based on the Restricted View policy. If an object is created without specifying anything in the column(s) used in the Restricted View policies, the object's visibility will depend on those policies, which could result in it being hidden from everyone.

What are the consequences of changing a materialization's column names on Ontology edits?¶

Changing the materializations only affects the materializations themselves and anything downstream. It will not affect the edits information stored in Object Storage V2.

What are `geohash` properties?¶

Geohash properties are a legacy type that was used in the Ontology to represent geospatial data. They have been renamed to geopoint for improved clarity, without any functional changes.

如何编辑OSv2对象类型的物化受限视图(Restricted View, RV)上的细粒度策略？¶

要编辑OSv2对象类型的物化受限视图(Restricted View, RV)上的细粒度策略，您必须编辑该对象类型所依赖的受限视图(RV)上的策略，这些策略随后会传播到物化受限视图。

是否可以通过用RID数组填充属性的方式，将多个非结构化文件附加到一个对象上？¶

不可以，无法通过这种方式附加文件。您需要通过操作(Action)显式地建立附件的父子关系。

在多数据源对象(MDO object)中，将列在两个受限视图(Restricted View)之间移动是否会改变属性的API名称和RID？¶

在受限视图之间移动列时，标识符将保持不变，因此属性API名称和属性RID不会改变。

在编辑冲突解决策略选择"应用最新值(Apply most recent value)"的情况下，如果用户编辑了一个之前为`null`的字段，并且管道运行后该字段在管道中仍为`null`，那么该属性将显示什么？¶

当管道运行时，如果时间戳(timestamp)属性更新为比编辑时间更新的时间戳，则该属性将恢复为null。如果时间戳属性保持不变（或为null），则用户的编辑将生效。

如何在不将属性转换为字符串的情况下，在操作表单(Action form)中将`true`或`false`映射为"是"或"否"？¶

这可以通过布尔属性配置的约束(Constraints)部分实现，选择多项选择(Multiple choice)和手动定义选项(Define options manually)，然后为true和false设置不同的显示值。

时间戳： 2024年6月26日

如果通过操作(Action)创建了一个新对象，并且该对象由受限视图(Restricted View)支持，那么它是否对所有用户可见？在特定列中指定值是否会根据该列限制访问？¶

是的，对象的可见性基于受限视图策略。如果在创建对象时未在受限视图策略所使用的列中指定任何值，则对象的可见性将取决于这些策略，这可能导致该对象对所有用户隐藏。

更改物化(Materialization)的列名对本体论(Ontology)编辑有什么影响？¶

更改物化仅影响物化本身及其下游内容。它不会影响存储在对象存储V2(Object Storage V2)中的编辑信息。

什么是`geohash`属性？¶

Geohash属性是一种遗留类型，曾用于本体论(Ontology)中表示地理空间数据。为提升清晰度，它们已更名为geopoint，功能上没有任何变化。
