元雪崩中的resource_type_id是什么？

Question

我是新来的dspace。我正在从dspace元雪崩表中检索值。我不明白的一个问题是元雪崩表中的resource_type_id。Resource_type_id具有特定的值。它的集合名称和描述值为3，比特流为0。这些值代表什么？

resource_type_id数据库表中DSpace列中的值引用org.dspace.core.Constants类中的常量：https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/core/Constants.java#L20
