Introduction 122 Network space measurement is based on certain methods, techniques and 123 standards. It uses software or hardware tools to test the 124 composition, behavior and development of cyberspace by testing 125 multiple indicators that characterize the state, property and 126 relationships of various layers of cyberspace. The range of 127 measurement can be local to the network space or global. The objects 128 to be measured include the composition, structure, property, 129 behavior, characteristics, laws and trends of the network space. The 130 information obtained by measurement is a kind of typical big data. 131 The content is diverse in format, complex in structure and rapid in 132 change. It is difficult to understand, interact with, and 133 disseminate the information. 135 Given that network measurement data may be used by many people other 136 than producers. It is usually produced by an individual or 137 organization and used by others or organizations. Building a unified 138 entity encoding rule enables people or organizations that are less 139 familiar with each other to better share data and use the data 140 appropriately. As web measurement data producers and users process 141 more and more data, appropriate textual data can provide them with 142 rich information about the data, enabling them to better manage, 143 store, share, update and reuse data products. 145 This memo can support the integration and management of surveying and 146 mapping information across departments, cross-domains, time space, 147 multi-source and multi-scale networks through the unified description 148 of network space property. It can be used as cyberspace management 149 in the future. It adopts a markup language RDF for describing 150 network resource property, and focuses on the classification and 151 coding rules of network measurement elements and their expansion 152 methods. 154 2. Terminology and Definition 156 2.1. Terminology and Definition 158 In this memo, individuals represent the objects of interest in the 159 field of network mapping space, and OWL does not use the Unique Name 160 Assumption. It must clearly indicate whether individuals are 161 identical, otherwise their relationship is unclear. 163 Note: Individuals are sometimes referred to as Instances. 165 2.2. Property 167 Properties are binary relationships between individuals. In the 168 description logic, the concept of a Role is represented. Properties 169 can be divided into the following categories: 171 Functional property 173 Functional property can only be connected to one individual. 175 Inverse Functional Property 177 The inverse functional property is that for a given individual, only 178 at most one individual can be connected through this property. That 179 is, the inverse property of this property is a functional property. 181 Inverse Property 183 The inverse property uses only one property name as a parameter, 184 indicating the inversion of the relationship. 186 Transitive Property 188 Transitive property means that the property can be passed. 190 Object Property 191 The Object property represents the relationship between instances of 192 two classes. 194 Datatype Property 196 Connect individual and XML Schema data type values or RDF literals, 197 Datatype property cannot be passed, symmetric, or inverse functional. 199 2.3. Cyberspace Feature 201 Cyberspace is a virtual and real space where human beings use 202 information facilities to construct and realize the information 203 interaction, and then influence human thoughts and behaviors. It 204 relies on the carrier of information and communication technology 205 infrastructure carriers such as Internet, telecommunication networks, 206 and various control systems and devices. 208 In cyberspace, the use of cyberspace means to detect and perceive 209 entities, including the Internet, telecommunications networks, 210 industrial control networks and other types of network resources. 211 Specifically, cyberspace resources include physical equipment such as 212 network infrastructure and network access; information resources and 213 network services such as audio, video, websites and text data; 214 virtual characters, various IP-based telecommunication network 215 equipment and industrial control systems, etc. 217 The feature is an abstract representation of an entity. Note: 218 Features can appear as types or as instances. When expressing only 219 one meaning, you should use a feature type or a feature instance.A 220 single cyberspace resource object existing in cyberspace is a 221 specific unit of cyberspace resource feature, and it is also the 222 smallest component of the corresponding feature types, and can be 223 represented by specific symbols. 225 3. Symbol and Abbreviation 227 RDF: Resource Description Framework 229 RDFS: Resource Description Framework Schema 231 XML: Extensible Markup Language 233 OWL: Ontology Web Language 235 URI: Uniform Resource Identifier 237 DTD: Document Type Definition 238 IDL: Interface Description Language 240 OCL: Object Constraint Language 242 4. Use cases 244 The following sections highlight some of the most common framework 245 for network resource property description use case scenarios and are 246 in no way exhaustive. 248 4.1. Intelligent semantic search 250 The traditional search method mainly uses keyword matching to realize 251 the retrieval of information. Therefore, it is difficult for the 252 user to simply use the keyword or keyword string to retrieve the 253 content that he really needs, and the natural language changes with 254 time, region or field. The same concept can be expressed in 255 different language expressions. For the same concept retrieval, 256 different users may use different keywords to query, resulting in a 257 large amount of irrelevant information being returned to the user. 259 Intelligent semantic search based on framework for network resource 260 property description is an advanced form of information retrieval, 261 which can provide users with search results in an accurate and 262 concise natural language. When the user initiates the query, the 263 search engine will provides unique identities for each resource, map 264 to parse and reason the keywords of the user query, and then map it 265 to one or a set of concepts, and then according to the concept level 266 in the framework. 268 4.2. Network security situational awareness 270 There are many elements involved in cyber security. These elements 271 often play a role in the attack threat. According to the order of 272 context, the layers are progressive, and finally reflect the macro 273 network security situation. The purpose of each element is 274 different, and the network security situation process can be divided 275 into several situational segments. Various situational elements are 276 extracted through network security events. 278 Network security situational awareness based on framework for network 279 resource property description can be regarded as a specific 280 situational segment. Through the structure of the security 281 situational, the role of various situational elements is 282 hierarchically displayed, enabling managers to grasp the current 283 network security more deeply and accurately. 285 4.3. Network Security 287 Network viruses and worms themselves are also a kind of network 288 resources. With the deepening of network opening and complexity, 289 network viruses and worms are evolving constantly, and the 290 characteristics of diversity and spatial discretization are 291 increasing, resulting in a great hidden danger of network security. 293 The framework for network resources categorization can locate the 294 network resources more accurately and distinguish the benign or 295 malignant network resources, study the process of virus evolution and 296 the possible effects according to the attached attributes , and 297 provide a clearer way to safeguard the operation of network space 298 security, such as anti virus, antivirus and so on. 300 5. Methodology for Network Resources Attribute Description 302 5.1. Basic Principles 304 5.1.1. Scientific principle 306 The attribute description should conform to the basic organizational 307 rules of cyberspace resource mapping information. The selection of 308 attribute classification perspective should meet the integration 309 requirements of multi-source cyberspace resource mapping information, 310 and fully take into account the traditional information 311 classification system in various fields, thus covering network 312 mapping information at various levels and fields. 314 5.1.2. Systematic principle 316 The methodology of Attribute description should be designed with good 317 compatibility and can cover the requirements of the attribute 318 representation of network measuring and mapping feature of different 319 scales, different properties and different types. The attribute 320 categorization system should correctly reflect the measuring and 321 mapping feature and the vertical and horizontal architecture 322 attributes. The level of information categorization and grading 323 should be clear and reasonable. The same perspective should be 324 adopted for the categorization of objects at the same level. 326 5.1.3. Consistency principle 328 The design of attribute categorization and description should meet 329 the uniqueness of the measuring and mapping feature attributes of 330 cyberspace resources in the same mapping system, in which the values 331 and units of the physical domain, logical domain and cognitive domain 332 attributes of entities should be consistent with the national and 333 international standards in related fields. When the scale of 334 resources and attributes in cyberspace is modified and redirected, 335 the description of resource attributes and the relationship between 336 resources and attributes should be stable and semantically 337 consistent. 339 5.1.4. Scalability principle 341 The attribute description, meta property description, resource- 342 attribute relationship description and attribute-attribute 343 relationship description of cyberspace resources are able to perfect 344 and expand when facing the future development of cyberspace, multi- 345 domain information integration and sharing, mapping of unknown 346 resources and user requirements in different fields. 348 5.2. Attribute description framework 350 In this memo, the attributes of cyberspace resources are described by 351 RDF resource description framework, and metadata is described as a 352 data model through XML syntax and RDFS. The basic RDF specification 353 only defines the rules, and does not define the vocabularies for 354 describing resources. It should be refined for practical application 355 in different fields. 357 RDF uses Web identifiers (URI) to identify things, and attributes and 358 attribute values to describe resources, allowing RDF to represent one 359 or more simple statements about resources as a graph of nodes and 360 arcs, where nodes represent resource and attribute values and arcs 361 represent attributes. 363 The RDF description for the cyberspace resource attribute consists of 364 a file, resource description, and statement three-level structure, 365 which is serialized by RDF/XML syntax. A file can contain multiple 366 resource descriptions, and a resource description can contain 367 multiple statements, a statement can be expressed as a triplet 368 composed of {subject, predicate, object} in natural language. In the 369 cyberspace resource and the attribute description, the cyberspace 370 resource entity is corresponding to the subject in the triplet, the 371 cyberspace attribute type is corresponding to the predicate in the 372 triplet, and the attribute value is corresponding to the object in 373 the triplet, which constitute the{cyberspace resource entity, 374 cyberspace attribute type, attribute value} triplet can accurately 375 and unambiguously record and describe all the information obtained 376 during the measuring and mapping process. 378 5.3. Description of association rules for attributes description 380 The association rules of attributes represent the internal relations 381 between attributes, and the possible associations or relations 382 between things can be found behind the data. Unsupervised machine 383 learning methods commonly found in data mining can be used for 384 knowledge discovery and building knowledge maps. In this memo, 385 various attribute association operations are defined: alias 386 relationship, synonym relationship, ownership relationship, and 387 aggregation relationship. 389 5.3.1. Alias relationship 391 1) Relationship name: ch: Alias 393 2) Relational meaning: representing different names of the same 394 attribute 396 3) Constraints: optional 398 4) Range: no specific requirements 400 5.3.2.

Framework for Network Resources Attribute Description 529 According to the state, structure and behavior characteristics of 530 resources at different levels in cyberspace, this memo divides the 531 properties of resources in cyberspace into four categories, namely 532 physical domain, logical domain, cognitive domain and social domain, 533 which are respectively used to describe the explicit and partial 534 implicit characteristics of resources at corresponding levels. In 535 addition to representing the properties of cyberspace resources, the 536 memo also includes nine meta property, which represent the common 537 features of attributes. The attribute description specifies its 538 meaning, data type, range of values, and so on as much as possible. 540 6.1. Physical domain attributes 542 The physical domain attribute represents a subset of features that 543 can be observed, queried, recorded, and measured in the physical 544 space and geospatial of each resource feature constituting the 545 cyberspace. Each attribute value is closely related to the objective 546 existence of the corresponding resource feature in the physical 547 world. Resources are at a higher level, the material basis of 548 services.
